Description

class Gio.UnixCredentialsMessage : Gio.SocketControlMessage {
  parent_instance: GSocketControlMessage,
  priv: GUnixCredentialsMessagePrivate*
}

This GSocketControlMessage contains a GCredentials instance. It may be sent using g_socket_send_message() and received using g_socket_receive_message() over UNIX sockets (ie: sockets in the G_SOCKET_FAMILY_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 g_socket_get_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.

Methods inherited from GSocketControlMessage (4)

g_socket_control_message_get_level

Returns the “level” (i.e. the originating protocol) of the control message. This is often SOL_SOCKET.

since: 2.22

g_socket_control_message_get_msg_type

Returns the protocol specific type of the control message. For instance, for UNIX fd passing this would be SCM_RIGHTS.

since: 2.22

g_socket_control_message_get_size

Returns the space required for the control message, not including headers or alignment.

since: 2.22

g_socket_control_message_serialize

Converts the data in the message to bytes placed in the message.
