NAME

       gss_get_mic - API function

SYNOPSIS

       #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);

ARGUMENTS

       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 qop_req
                   (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
                     GSS_S_BAD_QOP.

       const gss_buffer_t message_buffer
                   (buffer, opaque, read) Message to be protected.

       gss_buffer_t message_token
                   (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().

DESCRIPTION

       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.

RETURN VALUE

       `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.
