Yes and no.
    No there is no IPC implemented by glib.
    Yes you can easily achieve IPC while using glib based apps.

Generaly, an ipc implementation will give you a file descriptor for
incomming events, feed that file descriptor to g_io_channel_unix_new()
and that "channel" in turn to g_io_channel_add_watch().
