gss_get_mic - API function
OM_uint32 gss_get_mic(OM_uint32 * minor_status, const gss_ctx_id_t
context_handle, gss_qop_t qop_req, const gss_buffer_t message_buffer,
OM_uint32 * minor_status
(Integer, modify) Mechanism specific status code.
const gss_ctx_id_t context_handle
(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
to accept the default quality of protection offered by
mechanism, which may be requested by specifying
for this parameter. If an unsupported protection
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
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 mechanism.
