receiveCredentials
Receives credentials from the sending end of the connection. The sending end has to call g_unix_connection_send_credentials() (or similar) for this to work.
As well as reading the credentials this also reads (and discards) a single byte from the stream, as this is required for credentials passing to work on some implementations.
This method can be expected to be available on the following platforms:
Linux since GLib 2.26
FreeBSD since GLib 2.26
GNU/kFreeBSD since GLib 2.36
Solaris, Illumos and OpenSolaris since GLib 2.40
GNU/Hurd since GLib 2.40
Other ways to exchange credentials with a foreign peer includes the #GUnixCredentialsMessage type and g_socket_get_credentials() function.
Return
Received credentials on success (free with g_object_unref()), null if @error is set.
Since
2.26
Parameters
A #GCancellable or null.
