## Detailed Description

UnixCredentialsMessage - A SocketControlMessage containing credentials.

This SocketControlMessage contains a Credentials instance. It may be sent using Gio::Socket::send() and received using Gio::Socket::receive() over UNIX sockets (ie: sockets in the Gio::SOCKET_FAMILY_UNIX family).

For an easier way to send and receive credentials over stream-oriented UNIX sockets, see Gio::UnixConnection::send_credentials() and Gio::UnixConnection::receive_credentials(). To receive credentials of a foreign process connected to a socket, use Gio::Socket::get_credentials().

Since glibmm 2.28:
