g_unix_connection_send_credentials (
  GUnixConnection* connection,
  GCancellable* cancellable,
  GError** error


Passes the credentials of the current user the receiving side of the connection. The receiving end has to call g_unix_connection_receive_credentials() (or similar) to accept the credentials.

As well as sending the credentials this also writes a single NUL byte to 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.
