.SH DESCRIPTION
.sp
.LP
The \fBgss_process_context_token()\fR function provides a way to pass an
asynchronous token to the security service. Most context-level tokens are
emitted and processed synchronously by \fBgss_init_sec_context()\fR and
\fBgss_accept_sec_context()\fR, and the application is informed as to whether
further tokens are expected by the \fBGSS_C_CONTINUE_NEEDED\fR major status
bit. Occasionally, a mechanism might need to emit a context-level token at a
point when the peer entity is not expecting a token. For example, the
initiator's final call to \fBgss_init_sec_context()\fR may emit a token and
return a status of \fBGSS_S_COMPLETE\fR, but the acceptor's call to
\fBgss_accept_sec_context()\fR might fail. The acceptor's mechanism might want
to send a token containing an error indication to the initiator, but the
initiator is not expecting a token at this point, believing that the context is
fully established. \fBgss_process_context_token()\fR provides a way to pass
such a token to the mechanism at any time.
.sp
.LP
This function is provided for compatibility with the \fBGSS-API\fR version 1.
Because \fBgss_delete_sec_context()\fR no longer returns a valid
\fIoutput_token\fR to be sent to \fBgss_process_context_token()\fR,
applications using a newer version of the \fBGSS-API\fR do not need to rely on
this function.
.SH PARAMETERS

The parameter descriptions for \fBgss_process_context_token()\fR are as
follows:
.sp
.ne 2
.na
\fB\fIminor_status\fR\fR
.ad
.RS 18n
A mechanism-specific status code.

\fB\fIcontext_handle\fR\fR
.ad
.RS 18n
Context handle of context on which token is to be processed.
.RE

.sp
.ne 2
.na
\fB\fItoken_buffer\fR\fR
.ad
.RS 18n
Token to process.
.RE

.SH ERRORS
.sp
.LP
\fBgss_process_context_token()\fR returns one of the following status codes:
.sp
.ne 2
.na
\fB\fBGSS_S_COMPLETE\fR\fR
.ad
.RS 25n
Successful completion.
.RE

.sp
.ne 2
.na
\fB\fBGSS_S_DEFECTIVE_TOKEN\fR\fR
.ad
.RS 25n
Indicates that consistency checks performed on the token failed.
.RE

.sp
.ne 2
.na
\fB\fBGSS_S_NO_CONTEXT\fR\fR
.ad
.RS 25n
The \fIcontext_handle\fR did not refer to a valid context.
.RE

.sp
.ne 2
.na
\fB\fBGSS_S_FAILURE\fR\fR
.ad
.RS 25n
The underlying mechanism detected an error for which no specific \fBGSS\fR
status code is defined.  The mechanism-specific status code reported by means
of the \fIminor_status\fR parameter details the error condition.
