GSS_DELETE_SEC_CONTEXT(3GSS) Generic Security Services API Library Functions GSS_DELETE_SEC_CONTEXT(3GSS)

gss_delete_sec_context - delete a GSS-API security context

cc [ flag... ] file... -lgss  [ library... ]
#include <gssapi/gssapi.h>
OM_uint32 gss_delete_sec_context(OM_uint32 *minor_status,


     gss_ctx_id_t *context_handle,gss_buffer_t output_token);

Use the gss_delete_sec_context() function to delete a security context. The gss_delete_sec_context() 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 context_handle.

In addition to deleting established security contexts, gss_delete_sec_context() will delete any half-built security contexts that result from incomplete sequences of calls to gss_init_sec_context(3GSS) and gss_accept_sec_context(3GSS).

The Solaris implementation of the GSS-API retains the output_token parameter for compatibility with version 1 of the GSS-API. Both peer applications should invoke gss_delete_sec_context(), passing the value GSS_C_NO_BUFFER to the output_token parameter; this indicates that no token is required. If the application passes a valid buffer to gss_delete_sec_context(), it will return a zero-length token, indicating that no token should be transferred by the application.

The parameter descriptions for gss_delete_sec_context() follow:

minor_status

A mechanism specific status code.

context_handle

Context handle identifying specific context to delete. After deleting the context, the GSS-API will set context_handle to GSS_C_NO_CONTEXT.

output_token

A token to be sent to remote applications that instructs them to delete the context.

gss_delete_sec_context() may return the following status codes:

GSS_S_COMPLETE

Successful completion.

GSS_S_NO_CONTEXT

No valid context was supplied.

GSS_S_FAILURE

The underlying mechanism detected an error for which no specific GSS status code is defined. The mechanism-specific status code reported by means of the minor_status parameter details the error condition.
