NAME

       gss_process_context_token - API function

SYNOPSIS

       #include <gss.h>

       OM_uint32 gss_process_context_token(OM_uint32 * minor_status, const gss_ctx_id_t context_handle, const gss_buffer_t token_buffer);

ARGUMENTS

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

       const gss_ctx_id_t context_handle
		   (gss_ctx_id_t, read) Context handle of context on
		     which token is to be processed

       const gss_buffer_t token_buffer
		   (buffer, opaque, read) Token to process.

DESCRIPTION

       Provides a way to pass an asynchronous token to the security service.  Most context-level tokens are emitted and processed synchronously by
       gss_init_sec_context and gss_accept_sec_context, and the application is	informed  as  to  whether  further  tokens  are  expected  by  the
       GSS_C_CONTINUE_NEEDED  major  status bit.  Occasionally, a mechanism may need to emit a context-level token at a point when the peer entity
       is not expecting a token.  For example, the initiator's final call to gss_init_sec_context  may	emit  a  token	and  return  a	status	of
       GSS_S_COMPLETE,	but  the acceptor's call to gss_accept_sec_context may fail.  The acceptor's mechanism may wish to send a token containing
       an error indication to the initiator, but the initiator is not expecting a token at this point, believing that the context is fully  estab-
       lished.	Gss_process_context_token provides a way to pass such a token to the mechanism at any time.

RETURN VALUE

       `GSS_S_COMPLETE`: Successful completion.

       `GSS_S_DEFECTIVE_TOKEN`: Indicates that consistency checks performed on the token failed.

       `GSS_S_NO_CONTEXT`: The context_handle did not refer to a valid context.
