Method

GioDBusConnectionclose

since: 2.26

Declaration 

void
g_dbus_connection_close (
  GDBusConnection* connection,
  GCancellable* cancellable,
  GAsyncReadyCallback callback,
  gpointer user_data
)

Description

Closes connection. Note that this never causes the process to exit (this might only happen if the other end of a shared message bus connection disconnects, see GDBusConnection:exit-on-close).

Once the connection is closed, operations such as sending a message will return with the error G_IO_ERROR_CLOSED. Closing a connection will not automatically flush the connection so queued messages may be lost. Use g_dbus_connection_flush() if you need such guarantees.

If connection is already closed, this method fails with G_IO_ERROR_CLOSED.

When connection has been closed, the GDBusConnection::closed signal is emitted in the [thread-default main context][g-main-context-push-thread-default] of the thread that connection was constructed in.

This is an asynchronous method. When the operation is finished, callback will be invoked in the [thread-default main context][g-main-context-push-thread-default] of the thread you are calling this method from. You can then call g_dbus_connection_close_finish() to get the result of the operation. See g_dbus_connection_close_sync() for the synchronous version.
