Credentials

The GCredentials type is a reference-counted wrapper for native credentials.

The information in GCredentials 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. method@Gio.Socket.get_credentials.

Some operating systems supports securely sending and receiving credentials over a Unix Domain Socket, see class@Gio.UnixCredentialsMessage, method@Gio.UnixConnection.send_credentials and method@Gio.UnixConnection.receive_credentials for details.

On Linux, the native credential type is a struct ucred - see the man:unix(7) for details. This corresponds to G_CREDENTIALS_TYPE_LINUX_UCRED.

On Apple operating systems (including iOS, tvOS, and macOS), the native credential type is a struct xucred. This corresponds to G_CREDENTIALS_TYPE_APPLE_XUCRED.

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.

Since GLib 2.72, on Windows, the native credentials may contain the PID of a process. This corresponds to G_CREDENTIALS_TYPE_WIN32_PID.
