Function
Giobus_get_sync
since: 2.26
Declaration [src]
GDBusConnection*
g_bus_get_sync (
GBusType bus_type,
GCancellable* cancellable,
GError** error
)
Description [src]
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 GDBusConnection object will (usually) have
the GDBusConnection:exit-on-close property set to TRUE.

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 aNULLGError*.The argument will be left initialized to NULLby the function 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.
