(gss_ctx_id_t, read) Identifies the context on
which the message will be sent.
(gss_qop_t, read, optional) Specifies requested quality
of protection. Callers are encouraged, on portability grounds,
to accept the default quality of protection offered by the chosen
mechanism, which may be requested by specifying GSS_C_QOP_DEFAULT
for this parameter. If an unsupported protection strength is
requested, gss_get_mic will return a major_status of
const gss_buffer_t message_buffer
(buffer, opaque, read) Message to be protected.
(buffer, opaque, modify) Buffer to receive token. The
application must free storage associated with this buffer after
use with a call to gss_release_buffer().
Generates a cryptographic MIC for the supplied message, and places
the MIC in a token for transfer to the peer application. The
qop_req parameter allows a choice between several cryptographic
algorithms, if supported by the chosen mechanism.
Since some application-level protocols may wish to use tokens
emitted by gss_wrap() to provide "secure framing", implementations
must support derivation of MICs from zero-length messages.
`GSS_S_COMPLETE`: Successful completion.
`GSS_S_CONTEXT_EXPIRED`: The context has already expired.
`GSS_S_NO_CONTEXT`: The context_handle parameter did not identify a
`GSS_S_BAD_QOP`: The specified QOP is not supported by the
