get_credentials

Returns the credentials of the foreign process connected to this socket, if any (e.

g. it is only supported for g_socket_family_unix sockets).

If this operation isn't supported on the OS, the method fails with the g_io_error_not_supported error. On Linux this is implemented by reading the so_peercred option on the underlying socket.

This method can be expected to be available on the following platforms:

• Linux since GLib 2.26
• OpenBSD since GLib 2.30
• Solaris, Illumos and OpenSolaris since GLib 2.40
• NetBSD since GLib 2.42
• macOS, tvOS, iOS since GLib 2.66

Other ways to obtain credentials from a foreign peer includes the UnixCredentialsMessage type and send_credentials / receive_credentials functions.

Parameters:

this

a Socket.

Returns:

null if throws is set, otherwise a Credentials object that must be freed with unref.
