gss_get_mic - API function
#include <gss.h>
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, gss_buffer_t message_token);
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 valid context.
`GSS_S_BAD_QOP`: The specified QOP is not supported by the mechanism.
