/**
 * The #GCredentials type is a reference-counted wrapper for native
 * credentials. This information is typically used for identifying,
 * authenticating and authorizing other processes.
 * 
 * Some operating systems supports looking up the credentials of the
 * remote peer of a communication endpoint - see e.g.
 * g_socket_get_credentials().
 * 
 * Some operating systems supports securely sending and receiving
 * credentials over a Unix Domain Socket, see
 * #GUnixCredentialsMessage, g_unix_connection_send_credentials() and
 * g_unix_connection_receive_credentials() for details.
 * 
 * On Linux, the native credential type is a struct ucred - see the
 * unix(7) man page for details. This corresponds to
 * %G_CREDENTIALS_TYPE_LINUX_UCRED.
 * 
 * On FreeBSD, Debian GNU/kFreeBSD, and GNU/Hurd, the native
 * credential type is a struct cmsgcred. This corresponds
 * to %G_CREDENTIALS_TYPE_FREEBSD_CMSGCRED.
 * 
 * On NetBSD, the native credential type is a struct unpcbid.
 * This corresponds to %G_CREDENTIALS_TYPE_NETBSD_UNPCBID.
 * 
 * On OpenBSD, the native credential type is a struct sockpeercred.
 * This corresponds to %G_CREDENTIALS_TYPE_OPENBSD_SOCKPEERCRED.
 * 
 * On Solaris (including OpenSolaris and its derivatives), the native
 * credential type is a ucred_t. This corresponds to
 * %G_CREDENTIALS_TYPE_SOLARIS_UCRED.
