       gss_delete_sec_context - API function


       #include <gss.h>

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


       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
                     It   is    recommended    that    applications    specify
                   GSS_C_NO_BUFFER for
                     this  parameter,  requesting  local  deletion only.  If a
                     parameter is provided by the application,  the  mechanism
                     return  a  token  in  it;  mechanisms that implement only
                     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


       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.


       ‘GSS_S_COMPLETE‘: Successful completion.

       ‘GSS_S_NO_CONTEXT‘: No valid context was supplied.
