Description [src]

Like g_dbus_connection_call_sync() but also takes and returns GUnixFDList objects. See g_dbus_connection_call_with_unix_fd_list() and g_dbus_connection_call_with_unix_fd_list_finish() for more details.

interface_name

Type: const gchar*

D-Bus interface to invoke method on.

The value is a NUL terminated UTF-8 string.
method_name

Type: const gchar*

The name of the method to invoke.

The data is owned by the caller of the function.
The value is a NUL terminated UTF-8 string.
parameters

Type: GVariant

A GVariant tuple with parameters for the method or NULL if not passing parameters.

The argument can be NULL.
The data is owned by the caller of the function.
reply_type

Type: GVariantType

The expected type of the reply, or NULL.

The argument can be NULL.
The data is owned by the caller of the function.
flags

Type: GDBusCallFlags

Flags from the GDBusCallFlags enumeration.

timeout_msec

Type: gint

The timeout in milliseconds, -1 to use the default timeout or G_MAXINT for no timeout.

fd_list

Type: GUnixFDList

A GUnixFDList or NULL.

The argument can be NULL.
The data is owned by the caller of the function.
out_fd_list

Type: GUnixFDList

Return location for a GUnixFDList or NULL.

The argument will be set by the function.
The argument can be NULL.
The instance takes ownership of the data, and is responsible for freeing it.
cancellable

Type: GCancellable

A GCancellable or NULL.

The argument can be NULL.
The data is owned by the caller of the function.
error

Type: GError **

The return location for a recoverable error.

The argument can be NULL.
If the return location is not NULL, then you must initialize it to a NULL GError*.
The argument will left initialized to NULL by the method if there are no errors.
In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.

Return value

Type: GVariant

NULL if error is set. Otherwise a non-floating GVariant tuple with return values. Free with g_variant_unref().

The caller of the method takes ownership of the data, and is responsible for freeing it.
