.TH GSS_DELETE_SEC_CONTEXT 3GSS "Jan 15, 2003"
.SH NAME
gss_delete_sec_context \- delete a GSS-API security context
.SH SYNOPSIS
.LP
.nf
\fBcc\fR [ \fIflag\fR... ] \fIfile\fR... \fB-lgss\fR [ \fIlibrary\fR... ]
#include <gssapi/gssapi.h>
\fBOM_uint32\fR \fBgss_delete_sec_context\fR(\fBOM_uint32 *\fR\fIminor_status\fR,
\fBgss_ctx_id_t *\fR\fIcontext_handle\fR,\fBgss_buffer_t\fR \fIoutput_token\fR);
.fi
.SH DESCRIPTION
.sp
.LP
Use the \fBgss_delete_sec_context()\fR function to delete a security context.
The \fBgss_delete_sec_context()\fR function will delete the local data
structures associated with the specified security context. You may not obtain
further security services that use the context specified by
\fIcontext_handle\fR.
.sp
.LP
In addition to deleting established security contexts,
\fBgss_delete_sec_context()\fR will delete any half-built security contexts
that result from incomplete sequences of calls to
\fBgss_init_sec_context\fR(3GSS) and \fBgss_accept_sec_context\fR(3GSS).
.sp
.LP
The Solaris implementation of the \fBGSS-API\fR retains the \fIoutput_token\fR
parameter for compatibility with version 1 of the \fBGSS-API\fR. Both peer
applications should invoke \fBgss_delete_sec_context()\fR, passing the value
\fBGSS_C_NO_BUFFER\fR to the \fIoutput_token\fR parameter; this indicates that
no token is required. If the application passes a valid buffer to
\fBgss_delete_sec_context()\fR, it will return a zero-length token, indicating
that no token should be transferred by the application.
.SH PARAMETERS
.sp
.LP
The parameter descriptions for \fBgss_delete_sec_context()\fR follow:
.sp
.ne 2
.na
\fB\fIminor_status\fR\fR
.ad
.RS 18n
A mechanism specific status code.
.RE
.sp
.ne 2
.na
\fB\fIcontext_handle\fR\fR
.ad
.RS 18n
Context handle identifying specific context to delete. After deleting the
context, the \fBGSS-API\fR will set \fIcontext_handle\fR to
\fBGSS_C_NO_CONTEXT\fR.
.RE
.sp
.ne 2
.na
\fB\fIoutput_token\fR\fR
.ad
.RS 18n
A token to be sent to remote applications that instructs them to delete the
context.
.RE
.SH ERRORS
.sp
.LP
\fBgss_delete_sec_context()\fR may return the following status codes:
.sp
.ne 2
.na
\fB\fBGSS_S_COMPLETE\fR\fR
.ad
.RS 20n
Successful completion.
.RE
.sp
.ne 2
.na
\fB\fBGSS_S_NO_CONTEXT\fR\fR
.ad
.RS 20n
No valid context was supplied.
.RE
.sp
.ne 2
.na
\fB\fBGSS_S_FAILURE\fR\fR
.ad
.RS 20n
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.
