65 parameter allows a choice between several cryptographic algorithms,
66 if supported by the chosen mechanism.
68 Since some application-level protocols may wish to use tokens emitted
71 to provide "secure framing",
72 implementations must support the wrapping of zero-length messages.

80 compatibility with applications using the GSS-API V1 interface.
81 A distinct entrypoint (as opposed to #define) is provided,
82 both to allow GSS-API V1 applications to link
83 and to retain the slight parameter type differences between the
84 obsolete versions of this routine and its current form.
