pub struct UnixCredentialsMessage { /* private fields */ }
Available on Unix only.
Expand description

This SocketControlMessage contains a Credentials instance. It may be sent using SocketExtManual::send_message() and received using SocketExtManual::receive_message() over UNIX sockets (ie: sockets in the SocketFamily::Unix family).

For an easier way to send and receive credentials over stream-oriented UNIX sockets, see g_unix_connection_send_credentials() and g_unix_connection_receive_credentials(). To receive credentials of a foreign process connected to a socket, use SocketExt::credentials().

Since GLib 2.72, GUnixCredentialMessage is available on all platforms. It requires underlying system support (such as Windows 10 with AF_UNIX) at run time.

Before GLib 2.72, <gio/gunixcredentialsmessage.h> belonged to the UNIX-specific GIO interfaces, thus you had to use the gio-unix-2.0.pc pkg-config file when using it. This is no longer necessary since GLib 2.72.

Properties

credentials

The credentials stored in the message.
