GSS_PROCESS_CONTEXT_TOKEN(3)  Programmer's Manual GSS_PROCESS_CONTEXT_TOKEN(3)

NAME
     gss_process_context_token -- Process a token on a security	context	from a
     peer application

SYNOPSIS
     #include <gssapi/gssapi.h>

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

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 established.
     gss_process_context_token() provides a way	to pass	such a token to	the
     mechanism at any time.

PARAMETERS
     minor_status    Mechanism specific	status code.

     context_handle  Context handle of context on which	token is to be pro-
		     cessed.

     token_buffer    Token to process.

RETURN VALUES
     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	con-
			    text
