Instance Method Details

#action_name_is_valid(action_name) ⇒ Boolean

Checks if action_name is valid.

action_name is valid if it consists only of alphanumeric characters, plus '-' and '.'. The empty string is not a valid action name.

It is an error to call this function with a non-utf8 action_name. action_name must not be nil.

Parameters:

  • action_name (String) —

    a potential action name

Returns:

  • (Boolean) —

    true if action_name is valid

#action_parse_detailed_name(detailed_name, action_name, target_value) ⇒ Boolean

Parses a detailed action name into its separate name and target components.

Detailed action names can have three formats.

The first format is used to represent an action name with no target value and consists of just an action name containing no whitespace nor the characters :, ( or ). For example: app.action.

The second format is used to represent an action with a target value that is a non-empty string consisting only of alphanumerics, plus - and .. In that case, the action name and target value are separated by a double colon (::). For example: app.action::target.

The third format is used to represent an action with any type of target value, including strings. The target value follows the action name, surrounded in parens. For example: app.action(42). The target value is parsed using g_variant_parse(). If a tuple-typed value is desired, it must be specified in the same way, resulting in two sets of parens, for example: app.action((1,2,3)). A string target can be specified this way as well: app.action('target'). For strings, this third format must be used if target value is empty or contains characters other than alphanumerics, - and ..

If this function returns true, a non-nil value is guaranteed to be returned in action_name (if a pointer is passed in). A nil value may still be returned in target_value, as the detailed_name may not contain a target.

If returned, the #GVariant in target_value is guaranteed to not be floating.

Parameters:

  • detailed_name (String) —

    a detailed action name

  • action_name (String) —

    the action name

  • target_value (GLib::Variant) —

    the target value, or nil for no target

Returns:

  • (Boolean) —

    true if successful, else false with error set

#action_print_detailed_name(action_name, target_value) ⇒ String

Formats a detailed action name from action_name and target_value.

It is an error to call this function with an invalid action name.

This function is the opposite of g_action_parse_detailed_name(). It will produce a string that can be parsed back to the action_name and target_value by that function.

See that function for the types of strings that will be printed by this function.

Parameters:

  • action_name (String) —

    a valid action name

  • target_value (GLib::Variant) —

    a #GVariant target value, or nil

Returns:

  • (String) —

    a detailed format string

#app_info_create_from_commandline(commandline, application_name, flags) ⇒ Gio::AppInfo

Creates a new GApp::Info from the given information.

Note that for commandline, the quoting rules of the Exec key of the freedesktop.org Desktop Entry Specification are applied. For example, if the commandline contains percent-encoded URIs, the percent-character must be doubled in order to prevent it from being swallowed by Exec key unquoting. See the specification for exact quoting rules.

Parameters:

  • commandline (Gio::filename) —

    the commandline to use

  • application_name (String) —

    the application name, or nil to use commandline

#app_info_launch_default_for_uri(uri, context) ⇒ Boolean

Utility function that launches the default application registered to handle the specified uri. Synchronous I/O is done on the uri to detect the type of the file if required.

The D-Bus–activated applications don't have to be started if your application terminates too soon after this function. To prevent this, use g_app_info_launch_default_for_uri_async() instead.

Parameters:

Returns:

  • (Boolean) —

    true on success, false on error.

#app_info_launch_default_for_uri_async(uri, context, cancellable, callback, user_data) ⇒ nil

Async version of g_app_info_launch_default_for_uri().

This version is useful if you are interested in receiving error information in the case where the application is sandboxed and the portal may present an application chooser dialog to the user.

This is also useful if you want to be sure that the D-Bus–activated applications are really started before termination and if you are interested in receiving error information from their activation.

Parameters:

  • uri (String) —

    the uri to show

  • context (Gio::AppLaunchContext) —

    an optional GApp::LaunchContext

  • cancellable (Gio::Cancellable) —

    true if the launch was successful, false if error is set

#app_info_reset_type_associations(content_type) ⇒ nil

Removes all changes to the type associations done by g_app_info_set_as_default_for_type(), g_app_info_set_as_default_for_extension(), g_app_info_add_supports_type() or g_app_info_remove_supports_type().

Parameters:

    a content type

Returns:

  • (nil)

#async_initable_newv_async(object_type, n_parameters, parameters, io_priority, cancellable, callback, user_data) ⇒ nil

Helper function for constructing GAsync::Initable object. This is similar to g_object_newv() but also initializes the object asynchronously.

Parameters:

  • object_type (GLib::Type) —

    a #GType supporting GAsync::Initable.

  • n_parameters (Integer) —

    the number of parameters in parameters

#bus_get(bus_type, cancellable, callback, user_data) ⇒ nil

Asynchronously connects to the message bus specified by bus_type.

When the operation is finished, callback will be invoked. You can then call g_bus_get_finish() to get the result of the operation.

This is an asynchronous failable function. See g_bus_get_sync() for the synchronous version.

Parameters:

  • bus_type (Gio::BusType) —

    a GBus::Type

  • cancellable (Gio::Cancellable) —

    a #GCancellable or nil

  • callback (Gio::AsyncReadyCallback) —

    a GAsync::ReadyCallback to call when the request is satisfied

  • user_data (GObject) —

    the data to pass to callback

Returns:

  • (nil)

#bus_get_finish(res) ⇒ Gio::DBusConnection

Finishes an operation started with g_bus_get().

The returned object is a singleton, that is, shared with other callers of g_bus_get() and g_bus_get_sync() for bus_type. In the event that you need a private message bus connection, use g_dbus_address_get_for_bus_sync() and g_dbus_connection_new_for_address() with G_DBUS_CONNECTION_FLAGS_AUTHENTICATION_CLIENT and G_DBUS_CONNECTION_FLAGS_MESSAGE_BUS_CONNECTION flags.

Note that the returned GDBus::Connection object will (usually) have the GDBus::Connection:exit-on-close property set to true.

Parameters:

  • res (Gio::AsyncResult) —

    a GAsync::Result obtained from the #GAsyncReadyCallback passed to g_bus_get()

Returns:

  • (Gio::DBusConnection) —

    a GDBus::Connection or nil if error is set. Free with g_object_unref().

#bus_get_sync(bus_type, cancellable) ⇒ Gio::DBusConnection

Synchronously connects to the message bus specified by bus_type. Note that the returned object may shared with other callers, e.g. if two separate parts of a process calls this function with the same bus_type, they will share the same object.

This is a synchronous failable function. See g_bus_get() and g_bus_get_finish() for the asynchronous version.

The returned object is a singleton, that is, shared with other callers of g_bus_get() and g_bus_get_sync() for bus_type. In the event that you need a private message bus connection, use g_dbus_address_get_for_bus_sync() and g_dbus_connection_new_for_address() with G_DBUS_CONNECTION_FLAGS_AUTHENTICATION_CLIENT and G_DBUS_CONNECTION_FLAGS_MESSAGE_BUS_CONNECTION flags.

Note that the returned GDBus::Connection object will (usually) have the GDBus::Connection:exit-on-close property set to true.

Parameters:

Returns:

  • (Gio::DBusConnection) —

    a GDBus::Connection or nil if error is set. Free with g_object_unref().

#bus_own_name(bus_type, name, flags, bus_acquired_handler, name_acquired_handler, name_lost_handler, user_data, user_data_free_func) ⇒ Integer

Starts acquiring name on the bus specified by bus_type and calls name_acquired_handler and name_lost_handler when the name is acquired respectively lost. Callbacks will be invoked in the [thread-default main context][g-main-context-push-thread-default] of the thread you are calling this function from.

You are guaranteed that one of the name_acquired_handler and name_lost_handler callbacks will be invoked after calling this function - there are three possible cases:

  • name_lost_handler with a nil connection (if a connection to the bus can't be made).

  • bus_acquired_handler then name_lost_handler (if the name can't be obtained)

  • bus_acquired_handler then name_acquired_handler (if the name was obtained).

When you are done owning the name, just call g_bus_unown_name() with the owner id this function returns.

If the name is acquired or lost (for example another application could acquire the name if you allow replacement or the application currently owning the name exits), the handlers are also invoked. If the GDBus::Connection that is used for attempting to own the name closes, then name_lost_handler is invoked since it is no longer possible for other processes to access the process.

You cannot use g_bus_own_name() several times for the same name (unless interleaved with calls to g_bus_unown_name()) - only the first call will work.

Another guarantee is that invocations of name_acquired_handler and name_lost_handler are guaranteed to alternate; that is, if name_acquired_handler is invoked then you are guaranteed that the next time one of the handlers is invoked, it will be name_lost_handler. The reverse is also true.

If you plan on exporting objects (using e.g. g_dbus_connection_register_object()), note that it is generally too late to export the objects in name_acquired_handler. Instead, you can do this in bus_acquired_handler since you are guaranteed that this will run before name is requested from the bus.

This behavior makes it very simple to write applications that wants to [own names][gdbus-owning-names] and export objects. Simply register objects to be exported in bus_acquired_handler and unregister the objects (if any) in name_lost_handler.

Parameters:

  • bus_type (Gio::BusType) —

    the type of bus to own a name on

  • name (String) —

    the well-known name to own

  • name_lost_closure (GObject::Closure) —

    #GClosure to invoke when name is lost or nil

Returns:

  • (Integer) —

    an identifier (never 0) that can be used with g_bus_unown_name() to stop owning the name.

#bus_unown_name(owner_id) ⇒ nil

Stops owning a name.

Note that there may still be D-Bus traffic to process (relating to owning and unowning the name) in the current thread-default GMain::Context after this function has returned. You should continue to iterate the GMain::Context until the GDestroy::Notify function passed to g_bus_own_name() is called, in order to avoid memory leaks through callbacks queued on the GMain::Context after it’s stopped being iterated.

Parameters:

  • owner_id (Integer) —

    an identifier obtained from g_bus_own_name()

Returns:

  • (nil)

#bus_unwatch_name(watcher_id) ⇒ nil

Stops watching a name.

Note that there may still be D-Bus traffic to process (relating to watching and unwatching the name) in the current thread-default GMain::Context after this function has returned. You should continue to iterate the GMain::Context until the GDestroy::Notify function passed to g_bus_watch_name() is called, in order to avoid memory leaks through callbacks queued on the GMain::Context after it’s stopped being iterated.

Parameters:

  • watcher_id (Integer) —

    An identifier obtained from g_bus_watch_name()

Returns:

  • (nil)

#bus_watch_name(bus_type, name, flags, name_appeared_handler, name_vanished_handler, user_data, user_data_free_func) ⇒ Integer

Starts watching name on the bus specified by bus_type and calls name_appeared_handler and name_vanished_handler when the name is known to have an owner respectively known to lose its owner. Callbacks will be invoked in the [thread-default main context][g-main-context-push-thread-default] of the thread you are calling this function from.

You are guaranteed that one of the handlers will be invoked after calling this function. When you are done watching the name, just call g_bus_unwatch_name() with the watcher id this function returns.

If the name vanishes or appears (for example the application owning the name could restart), the handlers are also invoked. If the GDBus::Connection that is used for watching the name disconnects, then name_vanished_handler is invoked since it is no longer possible to access the name.

Another guarantee is that invocations of name_appeared_handler and name_vanished_handler are guaranteed to alternate; that is, if name_appeared_handler is invoked then you are guaranteed that the next time one of the handlers is invoked, it will be name_vanished_handler. The reverse is also true.

This behavior makes it very simple to write applications that want to take action when a certain [name exists][gdbus-watching-names]. Basically, the application should create object proxies in name_appeared_handler and destroy them again (if any) in name_vanished_handler. g_bus_unwatch_name() to stop watching the name.

  • the mime subdirectory of every directory in $XDG_DATA_DIRS

This function is intended to be used when writing tests that depend on information stored in the MIME database, in order to control the data.

Typically, in case your tests use %G_TEST_OPTION_ISOLATE_DIRS, but they depend on the system’s MIME database, you should call this function with dirs set to nil before calling g_test_init(), for instance:

  // Load MIME data from the system
  g_content_type_set_mime_dirs (NULL);
  // Isolate the environment
  g_test_init (&argc, &argv, G_TEST_OPTION_ISOLATE_DIRS, NULL);

  …

  • (GLib::List<String>) —

    list of the registered content types

#dbus_address_escape_value(string) ⇒ String

Escape string so it can appear in a D-Bus address as the value part of a key-value pair.

For instance, if string is /run/bus-for-:0, this function would return /run/bus-for-%3A0, which could be used in a D-Bus address like unix:nonce-tcp:host=127.0.0.1,port=42,noncefile=/run/bus-for-%3A0.

Parameters:

    a valid D-Bus address string for bus_type or nil if error is set

#dbus_address_get_stream(address, cancellable, callback, user_data) ⇒ nil

Asynchronously connects to an endpoint specified by address and sets up the connection so it is in a state to run the client-side of the D-Bus authentication conversation. address must be in the D-Bus address format.

When the operation is finished, callback will be invoked. You can then call g_dbus_address_get_stream_finish() to get the result of the operation.

This is an asynchronous failable function. See g_dbus_address_get_stream_sync() for the synchronous version.

Returns:

  • (nil)

#dbus_address_get_stream_finish(res, out_guid) ⇒ Gio::IOStream

Finishes an operation started with g_dbus_address_get_stream().

A server is not required to set a GUID, so out_guid may be set to nil even on success.

Parameters:

  • res (Gio::AsyncResult) —

    A GAsync::Result obtained from the GAsyncReadyCallback passed to g_dbus_address_get_stream().

  • out_guid (String) —

    nil or return location to store the GUID extracted from address, if any.

Returns:

#dbus_address_get_stream_sync(address, out_guid, cancellable) ⇒ Gio::IOStream

Synchronously connects to an endpoint specified by address and sets up the connection so it is in a state to run the client-side of the D-Bus authentication conversation. address must be in the D-Bus address format.

A server is not required to set a GUID, so out_guid may be set to nil even on success.

This is a synchronous failable function. See g_dbus_address_get_stream() for the asynchronous version.

Parameters:

  • address (String) —

    A valid D-Bus address.

  • out_guid (String) —

    nil or return location to store the GUID extracted from address, if any.

  • cancellable (Gio::Cancellable) —

    A #GCancellable or nil.

Returns:

#dbus_error_encode_gerror(error) ⇒ String

Creates a D-Bus error name to use for error. If error matches a registered error (cf. g_dbus_error_register_error()), the corresponding D-Bus error name will be returned.

Otherwise the a name of the form org.gtk.GDBus.UnmappedGError.Quark._ESCAPED_QUARK_NAME.Code_ERROR_CODE will be used. This allows other GDBus applications to map the error on the wire back to a #GError using g_dbus_error_new_for_dbus_error().

This function is typically only used in object mappings to put a #GError on the wire. Regular applications should not use it.

Parameters:

  • error (GLib::Error) —

    A #GError.

Returns:

  • (String) —

    A D-Bus error name (never nil). Free with g_free().

#dbus_error_get_remote_error(error) ⇒ String

Gets the D-Bus error name used for error, if any.

This function is guaranteed to return a D-Bus error name for all #GErrors returned from functions handling remote method calls (e.g. g_dbus_connection_call_finish()) unless g_dbus_error_strip_remote_error() has been used on error.

Parameters:

  • error (GLib::Error) —

    a #GError

Returns:

  • (String) —

    an allocated string or nil if the D-Bus error name could not be found. Free with g_free().

#dbus_error_is_remote_error(error) ⇒ Boolean

Checks if error represents an error received via D-Bus from a remote peer. If so, use g_dbus_error_get_remote_error() to get the name of the error. false otherwise.

Parameters:

  • error (GLib::Error) —

    A #GError.

Returns:

  • (Boolean) —

    true if error represents an error from a remote peer,

#dbus_error_new_for_dbus_error(dbus_error_name, dbus_error_message) ⇒ GLib::Error

Creates a #GError based on the contents of dbus_error_name and dbus_error_message.

Errors registered with g_dbus_error_register_error() will be looked up using dbus_error_name and if a match is found, the error domain and code is used. Applications can use g_dbus_error_get_remote_error() to recover dbus_error_name.

If a match against a registered error is not found and the D-Bus error name is in a form as returned by g_dbus_error_encode_gerror() the error domain and code encoded in the name is used to create the #GError. Also, dbus_error_name is added to the error message such that it can be recovered with g_dbus_error_get_remote_error().

Otherwise, a #GError with the error code %G_IO_ERROR_DBUS_ERROR in the %G_IO_ERROR error domain is returned. Also, dbus_error_name is added to the error message such that it can be recovered with g_dbus_error_get_remote_error().

In all three cases, dbus_error_name can always be recovered from the returned #GError using the g_dbus_error_get_remote_error() function (unless g_dbus_error_strip_remote_error() hasn't been used on the returned error).

This function is typically only used in object mappings to prepare #GError instances for applications. Regular applications should not use it.

Parameters:

  • dbus_error_name (String) —

    D-Bus error name.

  • dbus_error_message (String) —

    D-Bus error message.

Returns:

  • (GLib::Error) —

    A #GQuark for an error domain.

  • error_code (Integer) —

    An error code.

#dbus_error_register_error_domain(error_domain_quark_name, quark_volatile, entries, num_entries) ⇒ nil

Helper function for associating a #GError error domain with D-Bus error names.

While quark_volatile has a volatile qualifier, this is a historical artifact and the argument passed to it should not be volatile.

Parameters:

  • error_domain_quark_name (String) —

    The error domain name.

  • quark_volatile (Integer) —

    A pointer where to store the #GQuark.

  • entries (Array<Gio::DBusErrorEntry>) —

    Number of items to register.

Returns:

  • (nil)

#dbus_error_strip_remote_error(error) ⇒ Boolean

Looks for extra information in the error message used to recover the D-Bus error name and strips it if found. If stripped, the message field in error will correspond exactly to what was received on the wire.

This is typically used when presenting errors to the end user.

Parameters:

  • error (GLib::Error) —

    A #GError.

Returns:

  • (Boolean) —

    true if information was stripped, false otherwise.

#dbus_error_unregister_error(error_domain, error_code, dbus_error_name) ⇒ Boolean

Destroys an association previously set up with g_dbus_error_register_error().

Parameters:

#dbus_escape_object_path(s) ⇒ String

This is a language binding friendly version of g_dbus_escape_object_path_bytestring().

Parameters:

  • s (String) —

    the string to escape

Returns:

  • (String) —

    an escaped version of s. Free with g_free().

#dbus_escape_object_path_bytestring(bytes) ⇒ String

Escapes bytes for use in a D-Bus object path component. bytes is an array of zero or more nonzero bytes in an unspecified encoding, followed by a single zero byte.

The escaping method consists of replacing all non-alphanumeric characters (see g_ascii_isalnum()) with their hexadecimal value preceded by an underscore (_). For example: foo.bar.baz will become foo_2ebar_2ebaz.

This method is appropriate to use when the input is nearly a valid object path component but is not when your input is far from being a valid object path component. Other escaping algorithms are also valid to use with D-Bus object paths.

This can be reversed with g_dbus_unescape_object_path().

Parameters:

  • bytes (Array<Integer>) —

    the string of bytes to escape

Returns:

  • (String) —

    an escaped version of bytes. Free with g_free().

#dbus_generate_guid ⇒ String

Generate a D-Bus GUID that can be used with e.g. g_dbus_connection_new().

See the D-Bus specification regarding what strings are valid D-Bus GUIDs. The specification refers to these as ‘UUIDs’ whereas GLib (for historical reasons) refers to them as ‘GUIDs’. The terms are interchangeable.

Note that D-Bus GUIDs do not follow RFC 4122.

Returns:

  • (String) —

    A valid D-Bus GUID. Free with g_free().

#dbus_gvalue_to_gvariant(gvalue, type) ⇒ GLib::Variant

Converts a #GValue to a #GVariant of the type indicated by the type parameter.

The conversion is using the following rules:

  • G_TYPE_STRING: 's', 'o', 'g' or 'ay'
  • G_TYPE_STRV: 'as', 'ao' or 'aay'
  • G_TYPE_BOOLEAN: 'b'
  • G_TYPE_UCHAR: 'y'
  • G_TYPE_INT: 'i', 'n'
  • G_TYPE_UINT: 'u', 'q'
  • G_TYPE_INT64: 'x'
  • G_TYPE_UINT64: 't'
  • G_TYPE_DOUBLE: 'd'
  • G_TYPE_VARIANT: Any GVariant::Type

This can fail if e.g. gvalue is of type %G_TYPE_STRING and type is 'i', i.e. %G_VARIANT_TYPE_INT32. It will also fail for any #GType (including e.g. %G_TYPE_OBJECT and %G_TYPE_BOXED derived-types) not in the table above.

Note that if gvalue is of type %G_TYPE_VARIANT and its value is nil, the empty #GVariant instance (never nil) for type is returned (e.g. 0 for scalar types, the empty string for string types, '/' for object path types, the empty array for any array type and so on).

See the g_dbus_gvariant_to_gvalue() function for how to convert a #GVariant to a #GValue.

Parameters:

  • gvalue (GObject::Value) —

    A #GValue to convert to a #GVariant

  • type (GLib::VariantType) —

    A GVariant::Type

Returns:

  • (GLib::Variant) —

    A #GVariant (never floating) of GVariant::Type type holding the data from gvalue or an empty #GVariant in case of failure. Free with g_variant_unref().

#dbus_gvariant_to_gvalue(value, out_gvalue) ⇒ nil

Converts a #GVariant to a #GValue. If value is floating, it is consumed.

The rules specified in the g_dbus_gvalue_to_gvariant() function are used - this function is essentially its reverse form. So, a #GVariant containing any basic or string array type will be converted to a #GValue containing a basic value or string array. Any other #GVariant (handle, variant, tuple, dict entry) will be converted to a #GValue containing that #GVariant.

The conversion never fails - a valid #GValue is always returned in out_gvalue.

Parameters:

  • value (GLib::Variant) —

    A #GVariant.

  • out_gvalue (GObject::Value) —

    Return location pointing to a zero-filled (uninitialized) #GValue.

Returns:

  • (nil)

#dbus_is_address(string) ⇒ Boolean

Checks if string is a D-Bus address.

This doesn't check if string is actually supported by GDBus::Server or GDBus::Connection - use g_dbus_is_supported_address() to do more checks.

Parameters:

  • string (String) —

    A string.

Returns:

  • (Boolean) —

    true if string is a valid D-Bus address, false otherwise.

#dbus_is_error_name(string) ⇒ Boolean

Check whether string is a valid D-Bus error name.

This function returns the same result as g_dbus_is_interface_name(), because D-Bus error names are defined to have exactly the same syntax as interface names.

Parameters:

  • string (String) —

    The string to check.

Returns:

  • (Boolean) —

    true if valid, false otherwise.

#dbus_is_guid(string) ⇒ Boolean

Checks if string is a D-Bus GUID.

See the documentation for g_dbus_generate_guid() for more information about the format of a GUID.

Parameters:

  • string (String) —

    The string to check.

Returns:

  • (Boolean) —

    true if string is a GUID, false otherwise.

#dbus_is_interface_name(string) ⇒ Boolean

Checks if string is a valid D-Bus interface name.

Parameters:

  • string (String) —

    The string to check.

Returns:

  • (Boolean) —

    true if valid, false otherwise.

#dbus_is_member_name(string) ⇒ Boolean

Checks if string is a valid D-Bus member (e.g. signal or method) name.

Parameters:

  • string (String) —

    The string to check.

Returns:

  • (Boolean) —

    true if valid, false otherwise.

#dbus_is_name(string) ⇒ Boolean

Checks if string is a valid D-Bus bus name (either unique or well-known).

Parameters:

    The string to check.

Returns:

  • (Boolean) —

    true if valid, false otherwise.

#dbus_is_supported_address(string) ⇒ Boolean

Like g_dbus_is_address() but also checks if the library supports the transports in string and that key/value pairs for each transport are valid. See the specification of the D-Bus address format. supported by this library, false if error is set.

Parameters:

  • string (String) —

    A string.

Returns:

  • (Boolean) —

    true if string is a valid D-Bus address that is

#dbus_is_unique_name(string) ⇒ Boolean

#dbus_unescape_object_path(s) ⇒ Array<Integer>

Unescapes an string that was previously escaped with g_dbus_escape_object_path(). If the string is in a format that could not have been returned by g_dbus_escape_object_path(), this function returns nil.

Encoding alphanumeric characters which do not need to be encoded is not allowed (e.g _63 is not valid, the string should contain c instead).

Parameters:

  • s (String) —

    the string to unescape

Returns:

  • (Array<Integer>) —

    an unescaped version of s, or nil if s is not a string returned from g_dbus_escape_object_path(). Free with g_free().

#dtls_client_connection_new(base_socket, server_identity) ⇒ Gio::DtlsClientConnection

Creates a new GDtls::ClientConnection wrapping base_socket which is assumed to communicate with the server identified by server_identity.

Parameters:

Returns:

Creates a new GDtls::ServerConnection wrapping base_socket.

Parameters:

Returns:

#file_new_build_filenamev(args) ⇒ Gio::File

Constructs a #GFile from a vector of elements using the correct separator for filenames.

Using this function is equivalent to calling g_build_filenamev(), followed by g_file_new_for_path() on the result.

Parameters:

  • args (Array<Gio::filename>) —

    nil-terminated array of strings containing the path elements.

Returns:

#file_new_for_commandline_arg(arg) ⇒ Gio::File

Creates a #GFile with the given argument from the command line. The value of arg can be either a URI, an absolute path or a relative path resolved relative to the current working directory. This operation never fails, but the returned object might not support any I/O operation if arg points to a malformed path.

Note that on Windows, this function expects its argument to be in UTF-8 -- not the system code page. This means that you should not use this function with string from argv as it is passed to main(). g_win32_get_command_line() will return a UTF-8 version of the commandline. #GApplication also uses UTF-8 but g_application_command_line_create_file_for_arg() may be more useful for you there. It is also always possible to use this function with GOption::Context arguments of type %G_OPTION_ARG_FILENAME.

Parameters:

  • arg (Gio::filename) —

    a command line string

Returns:

  • (Gio::File) —

    a new #GFile. Free the returned object with g_object_unref().

#file_new_for_commandline_arg_and_cwd(arg, cwd) ⇒ Gio::File

Creates a #GFile with the given argument from the command line.

This function is similar to g_file_new_for_commandline_arg() except that it allows for passing the current working directory as an argument instead of using the current working directory of the process.

This is useful if the commandline argument was given in a context other than the invocation of the current process.

See also g_application_command_line_create_file_for_arg().

Parameters:

  • arg (Gio::filename) —

    a command line string

  • cwd (Gio::filename) —

    the current working directory of the commandline

Returns:

#file_new_for_path(path) ⇒ Gio::File

Constructs a #GFile for a given path. This operation never fails, but the returned object might not support any I/O operation if path is malformed.

Parameters:

  • path (Gio::filename) —

    a string containing a relative or absolute path. The string must be encoded in the glib filename encoding.

Returns:

  • (Gio::File) —

    a new #GFile for the given path. Free the returned object with g_object_unref().

#file_new_for_uri(uri) ⇒ Gio::File

Constructs a #GFile for a given URI. This operation never fails, but the returned object might not support any I/O operation if uri is malformed or if the uri type is not supported.

Parameters:

  • uri (String) —

    a UTF-8 string containing a URI

Returns:

  • (Gio::File) —

    a new #GFile for the given uri. Free the returned object with g_object_unref().

#file_new_tmp(tmpl, iostream) ⇒ Gio::File

#io_error_from_errno(err_no) ⇒ Gio::IOErrorEnum

Converts errno.h error codes into GIO error codes.

The fallback value %G_IO_ERROR_FAILED is returned for error codes not currently handled (but note that future GLib releases may return a more specific value instead).

As errno is global and may be modified by intermediate function calls, you should save its value immediately after the call returns, and use the saved value instead of errno:

  int saved_errno;

  ret = read (blah);
  saved_errno = errno;

  g_io_error_from_errno (saved_errno);

#io_modules_scan_all_in_directory(dirname) ⇒ nil

Scans all the modules in the specified directory, ensuring that any extension point implemented by a module is registered.

This may not actually load and initialize all the types in each module, some modules may be lazily loaded and initialized when an extension point it implements is used with e.g. g_io_extension_point_get_extensions() or g_io_extension_point_get_extension_by_name().

If you need to guarantee that all types are loaded in all the modules, use g_io_modules_load_all_in_directory().

    pathname for a directory containing modules to scan.

Returns:

  • (nil)

#io_modules_scan_all_in_directory_with_scope(dirname, scope) ⇒ nil

Scans all the modules in the specified directory, ensuring that any extension point implemented by a module is registered.

This may not actually load and initialize all the types in each module, some modules may be lazily loaded and initialized when an extension point it implements is used with e.g. g_io_extension_point_get_extensions() or g_io_extension_point_get_extension_by_name().

If you need to guarantee that all types are loaded in all the modules, use g_io_modules_load_all_in_directory().

Returns:

  • (nil)

#io_scheduler_push_job(job_func, user_data, notify, io_priority, cancellable) ⇒ nil

Schedules the I/O job to run in another thread.

notify will be called on user_data after job_func has returned, regardless whether the job was cancelled or has run to completion.

If cancellable is not nil, it can be used to cancel the I/O job by calling g_cancellable_cancel() or by calling g_io_scheduler_cancel_all_jobs(). of the request.

Parameters:

  • job_func (Gio::IOSchedulerJobFunc) —

    a GIOScheduler::JobFunc.

  • user_data (GObject) —

    data to pass to job_func

#keyfile_settings_backend_new(filename, root_path, root_group) ⇒ Gio::SettingsBackend

Creates a keyfile-backed GSettings::Backend.

The filename of the keyfile to use is given by filename.

All settings read to or written from the backend must fall under the path given in root_path (which must start and end with a slash and not contain two consecutive slashes). root_path may be "/".

If root_group is non-nil then it specifies the name of the keyfile group used for keys that are written directly below root_path. For example, if root_path is "/apps/example/" and root_group is "toplevel", then settings the key "/apps/example/enabled" to a value of true will cause the following to appear in the keyfile:

|[ [toplevel] enabled=true ]|

If root_group is nil then it is not permitted to store keys directly below the root_path.

For keys not stored directly below root_path (ie: in a sub-path), the name of the subpath (with the final slash stripped) is used as the name of the keyfile group. To continue the example, if "/apps/example/profiles/default/font-size" were set to 12 then the following would appear in the keyfile:

|[ [profiles/default] font-size=12 ]|

The backend will refuse writes (and return writability as being false) for keys outside of root_path and, in the event that root_group is nil, also for keys directly under root_path. Writes will also be refused if the backend detects that it has the inability to rewrite the keyfile (ie: the containing directory is not writable).

There is no checking done for your key namespace clashing with the syntax of the key file format. For example, if you have '[' or ']' characters in your path names or '=' in your key names you may be in trouble.

The backend reads default values from a keyfile called defaults in the directory specified by the GKeyfile::SettingsBackend:defaults-dir property, and a list of locked keys from a text file with the name locks in the same location.

Parameters:

  • filename (String) —

    the filename of the keyfile

  • root_path (String) —

    the path under which all settings keys appear

  • root_group (String) —

    the group name corresponding to root_path, or nil

Returns:

#memory_monitor_dup_default ⇒ Gio::MemoryMonitor

Gets a reference to the default GMemory::Monitor for the system.

Returns:

#memory_settings_backend_new ⇒ Gio::SettingsBackend

Creates a memory-backed GSettings::Backend.

This backend allows changes to settings, but does not write them to any backing storage, so the next time you run your application, the memory backend will start out with the default values again.

Returns:

#network_monitor_get_default ⇒ Gio::NetworkMonitor

Gets the default GNetwork::Monitor for the system.

Returns:

  • (Gio::NetworkMonitor) —

    a GNetwork::Monitor, which will be a dummy object if no network monitor is available

#networking_init ⇒ nil

Returns:

  • (nil)

#null_settings_backend_new ⇒ Gio::SettingsBackend

Creates a readonly GSettings::Backend.

This backend does not allow changes to settings, so all settings will always have their default values.

Returns:

#pollable_source_new(pollable_stream) ⇒ GLib::Source

Utility method for GPollable::InputStream and #GPollableOutputStream implementations. Creates a new #GSource that expects a callback of type GPollable::SourceFunc. The new source does not actually do anything on its own; use g_source_add_child_source() to add other sources to it to cause it to trigger.

Parameters:

  • pollable_stream (GObject::Object) —

    the stream associated with the new source

Returns:

  • (GLib::Source) —

    the new #GSource.

#pollable_source_new_full(pollable_stream, child_source, cancellable) ⇒ GLib::Source

Utility method for GPollable::InputStream and #GPollableOutputStream implementations. Creates a new #GSource, as with g_pollable_source_new(), but also attaching child_source (with a dummy callback), and cancellable, if they are non-nil.

Parameters:

  • pollable_stream (GObject::Object) —

    the stream associated with the new source

  • child_source (GLib::Source) —

    optional child source to attach

  • cancellable (Gio::Cancellable) —

#pollable_stream_read(stream, buffer, count, blocking, cancellable) ⇒ Gio::gssize

Tries to read from stream, as with g_input_stream_read() (if blocking is true) or g_pollable_input_stream_read_nonblocking() (if blocking is false). This can be used to more easily share code between blocking and non-blocking implementations of a method.

If blocking is false, then stream must be a GPollable::InputStream for which g_pollable_input_stream_can_poll() returns true, or else the behavior is undefined. If blocking is true, then stream does not need to be a GPollable::InputStream.

Parameters:

  • stream (Gio::InputStream) —

    a GInput::Stream

  • buffer (Array<Integer>) —

    a buffer to read data into

  • count (Integer) —

    the number of bytes to read

  • cancellable (Gio::Cancellable) —

    optional #GCancellable object, nil to ignore.

Returns:

  • (Gio::gssize) —

    the number of bytes read, or -1 on error.

#pollable_stream_write(stream, buffer, count, blocking, cancellable) ⇒ Gio::gssize

Tries to write to stream, as with g_output_stream_write() (if blocking is true) or g_pollable_output_stream_write_nonblocking() (if blocking is false). This can be used to more easily share code between blocking and non-blocking implementations of a method.

If blocking is false, then stream must be a GPollable::OutputStream for which g_pollable_output_stream_can_poll() returns true or else the behavior is undefined. If blocking is true, then stream does not need to be a GPollable::OutputStream.

Parameters:

  • stream (Gio::OutputStream) —

    a GOutput::Stream.

  • buffer (Array<Integer>) —

    the buffer containing the data to write.

  • count (Integer) —

    the number of bytes to write

  • blocking (Boolean) —

    whether to do blocking I/O

  • cancellable (Gio::Cancellable) —

    optional #GCancellable object, nil to ignore.

Returns:

  • (Gio::gssize) —

    the number of bytes written, or -1 on error.

#pollable_stream_write_all(stream, buffer, count, blocking, bytes_written, cancellable) ⇒ Boolean

Tries to write count bytes to stream, as with g_output_stream_write_all(), but using g_pollable_stream_write() rather than g_output_stream_write().

On a successful write of count bytes, true is returned, and bytes_written is set to count.

If there is an error during the operation (including %G_IO_ERROR_WOULD_BLOCK in the non-blocking case), false is returned and error is set to indicate the error status, bytes_written is updated to contain the number of bytes written into the stream before the error occurred.

As with g_pollable_stream_write(), if blocking is false, then stream must be a GPollable::OutputStream for which g_pollable_output_stream_can_poll() returns true or else the behavior is undefined. If blocking is true, then stream does not need to be a GPollable::OutputStream.

Parameters:

  • stream (Gio::OutputStream) —

    a GOutput::Stream.

  • buffer (Array<Integer>) —

    the buffer containing the data to write.

  • count (Integer) —

    the number of bytes to write

  • blocking (Boolean) —

    whether to do blocking I/O

  • bytes_written (Integer) —

    location to store the number of bytes that was written to the stream

  • cancellable (Gio::Cancellable) —

    optional #GCancellable object, nil to ignore.

Returns:

  • (Boolean) —

    true on success, false if there was an error

#resource_load(filename) ⇒ Gio::Resource

Loads a binary resource bundle and creates a #GResource representation of it, allowing you to query it for data.

If you want to use this resource in the global resource namespace you need to register it with g_resources_register().

If filename is empty or the data in it is corrupt, %G_RESOURCE_ERROR_INTERNAL will be returned. If filename doesn’t exist, or there is an error in reading it, an error from g_mapped_file_new() will be returned.

Parameters:

  • filename (Gio::filename) —

    the path of a filename to load, in the GLib filename encoding

Returns:

  • (Gio::Resource) —

    a new #GResource, or nil on error

#resources_enumerate_children(path, lookup_flags) ⇒ Array<String>

Returns all the names of children at the specified path in the set of globally registered resources. The return result is a nil terminated list of strings which should be released with g_strfreev().

lookup_flags controls the behaviour of the lookup.

Parameters:

Returns:

  • (Array<String>) —

    an array of constant strings

#resources_get_info(path, lookup_flags, size, flags) ⇒ Boolean

Looks for a file at the specified path in the set of globally registered resources and if found returns information about it.

    A pathname inside the resource

  • lookup_flags (Gio::ResourceLookupFlags) —

    A GResource::LookupFlags

  • size (Integer) —

  • (Boolean) —

    true if the file was found. false if there were errors

#resources_lookup_data(path, lookup_flags) ⇒ GLib::Bytes

Looks for a file at the specified path in the set of globally registered resources and returns a #GBytes that lets you directly access the data in memory.

The data is always followed by a zero byte, so you can safely use the data as a C string. However, that byte is not included in the size of the GBytes.

For uncompressed resource files this is a pointer directly into the resource bundle, which is typically in some readonly data section in the program binary. For compressed files we allocate memory on the heap and automatically uncompress the data.

lookup_flags controls the behaviour of the lookup.

Parameters:

Returns:

  • (GLib::Bytes) —

    #GBytes or nil on error. Free the returned object with g_bytes_unref()

#resources_open_stream(path, lookup_flags) ⇒ Gio::InputStream

Looks for a file at the specified path in the set of globally registered resources and returns a GInput::Stream that lets you read the data.

lookup_flags controls the behaviour of the lookup.

Parameters:

Returns:

  • (Gio::InputStream) —

    GInput::Stream or nil on error. Free the returned object with g_object_unref()

#resources_register(resource) ⇒ nil

Registers the resource with the process-global set of resources. Once a resource is registered the files in it can be accessed with the global resource lookup functions like g_resources_lookup_data().

Parameters:

  • resource (Gio::Resource) —

    A #GResource

Returns:

  • (nil)

#resources_unregister(resource) ⇒ nil

Unregisters the resource from the process-global set of resources.

Parameters:

  • resource (Gio::Resource) —

    A #GResource

Returns:

  • (nil)

#settings_schema_source_get_default ⇒ Gio::SettingsSchemaSource

Gets the default system schema source.

This function is not required for normal uses of #GSettings but it may be useful to authors of plugin management systems or to those who want to introspect the content of schemas.

If no schemas are installed, nil will be returned.

The returned source may actually consist of multiple schema sources from different directories, depending on which directories were given in XDG_DATA_DIRS and GSETTINGS_SCHEMA_DIR. For this reason, all lookups performed against the default source should probably be done recursively.

Returns:
