.SH NAME
gss_process_context_token \- pass asynchronous token to security service
.SH SYNOPSIS
.LP
.nf
\fBcc\fR [ \fIflag\fR... ] \fIfile\fR... \fB-lgss\fR [ \fIlibrary\fR... ]
#include <gssapi/gssapi.h>
\fBOM_uint32\fR \fBgss_process_context_token\fR(\fBOM_uint32 *\fR\fIminor_status\fR,
\fBconst gss_ctx_id_t\fR \fIcontext_handle\fR,\fBconst gss_buffer_t\fR \fItoken_buffer\fR);
.fi
.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applications using a newer version of the \fBGSS-API\fR do not need to rely on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.

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

.ne 2
.mk
.na
\fB\fBGSS_S_NO_CONTEXT\fR\fR
.ad

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.
