gss_delete_sec_context -- Delete a security context 

C Prototype 

OM_uint32 gss_delete_sec_context(
      OM_uint32              minor_status,
      gss_ctx_id_t           context_handle,
      gss_buffer_t           output_token );

Arguments 

minor_status (output)		A mechanism-specific status code.
context_handle (input/output)
		A context handle identifying the context to delete. After deleting the context, the GSSAPI will set this context handle to GSS_C_NO_CONTEXT.
output_token (output)		A token to be sent to the remote application to instruct it to also delete the context. It is recommended that applications specify GSS_C_NO_BUFFER for this argument, requesting local deletion only. If a buffer argument is provided by the application, the mechanism will either return a token in it, or set the length field of this token to zero to indicate to the application that no token is to be sent to the peer.

Description 

This routine deletes a security context. The gss_delete_sec_context routine deletes the local data structures associated with the specified security context, and may generate an output_token, which when passed to the peer gss_process_context_token will instruct it to do likewise. No further security services may be obtained using the context specified by context_handle.

The output_token argument is retained for compatibility with Version 1 of the GSSAPI. It is recommended that both peer applications invoke gss_delete_sec_context passing the value GSS_C_NO_BUFFER for the output_token argument, indicating that no token is required, and that gss_delete_sec_context should simply delete local context data structures.

Return Values 

This routine returns one of the following GSS status codes:

GSS_S_COMPLETE	Successful completion.
GSS_S_FAILURE	Failure. See minor_status for more information.
GSS_S_NO_CONTEXT	No valid context was supplied.
