NAME

       gss_delete_sec_context - API function

SYNOPSIS

       #include <gss.h>

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

ARGUMENTS

       OM_uint32 * minor_status
                   (Integer, modify) Mechanism specific status code.

       gss_ctx_id_t * context_handle
                   (gss_ctx_id_t, modify) Context handle identifying
                     context to delete.  After deleting the context, the GSS-API will
                     set this context handle to GSS_C_NO_CONTEXT.

       gss_buffer_t output_token
                   (buffer, opaque, modify, optional) Token to be sent
                     to remote application to instruct it to also delete the context.
                     It is recommended that applications specify GSS_C_NO_BUFFER for
                     this parameter, requesting local deletion only.  If a buffer
                     parameter is provided by the application, the mechanism may
                     return a token in it; mechanisms that implement only local
                     deletion should 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

       Delete a security context.  gss_delete_sec_context will delete 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.  If no token is required by the mechanism, the
       GSS-API should set the length field of the output_token (if  provided)  to  zero.   No  further  security
       services may be obtained using the context specified by context_handle.

       In addition to deleting established security contexts, gss_delete_sec_context must also be able to delete
       "half-built"      security      contexts     resulting     from     an     incomplete     sequence     of
       gss_init_sec_context()/gss_accept_sec_context() calls.

       The output_token parameter is  retained  for  compatibility  with  version  1  of  the  GSS-API.   It  is
       recommended  that  both peer applications invoke gss_delete_sec_context passing the value GSS_C_NO_BUFFER
       for the output_token parameter, indicating that no token is  required,  and  that  gss_delete_sec_context
       should  simply  delete  local  context  data  structures.  If the application does pass a valid buffer to
       gss_delete_sec_context, mechanisms are encouraged to return a zero-length token, indicating that no  peer
       action is necessary, and that no token should be transferred by the application.

RETURN VALUE

       `GSS_S_COMPLETE`: Successful completion.

       `GSS_S_NO_CONTEXT`: No valid context was supplied.
