+.SH DESCRIPTION
+.sp
+.LP
+The \fBgss_get_mic()\fR function generates a cryptographic \fBMIC\fR for the supplied message, and places the \fBMIC\fR in a token for transfer to the peer application. The \fIqop_req\fR parameter allows a choice between several cryptographic algorithms, if supported by the chosen mechanism.
+.sp
+.LP
+Since some application-level protocols may wish to use tokens emitted by \fBgss_wrap\fR(3GSS) to provide secure framing, the \fBGSS-API\fR allows \fBMIC\fRs to be derived from zero-length messages.
+.SH PARAMETERS

+.sp
+.ne 2
+.mk
+.na
+\fB\fIminor_status\fR\fR
+.ad

+\fB\fIcontext_handle\fR\fR
+.ad
+.RS 18n
+.rt  
+Identifies the context on which the message will be sent.
+.RE

+.sp
+.ne 2
+.mk
+.na
+\fB\fIqop_req\fR\fR
+.ad
+.RS 18n
+.rt  
+Specifies the 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 \fBGSS_C_QOP_DEFAULT\fR for this parameter. If an unsupported protection strength is requested, \fBgss_get_mic()\fR will return a \fImajor_status\fR of \fBGSS_S_BAD_QOP\fR.

+.RS 18n
+.rt  
+The buffer to receive the token. Storage associated with this message must be freed by the application after use with a call to \fBgss_release_buffer\fR(3GSS).
