acnet_request

	status.i4.v = acnet_request(task.i1a.r, dest_node.i2.v, dest_task.i1a.r,
				    request_buffer.g.v, request_length.u4.v,
				    request_flags.u2.v, request_id.u2.r)

	This routine sends an ACNET request.  The reply will be pushed onto
	a FIFO stack for later access with 'acnet_get_reply'.  This routine
	should be preceded by a call to 'acnet_connect'.

	task		ASCII task name (PROCESS_NAME_LEN characters)
			(name used in 'acnet_connect' call)
	dest_node	target ACNET logical node
			(constants are in nodedefs)
	dest_task	target ASCII task name (PROCESS_NAME_LEN characters)
	request_buffer	request buffer
	request_length	request length in bytes (only even lengths allowed)
	request_flags	ACNET request flags
			(REQ_M_NORMAL -> no special conditions,
			 REQ_M_MULTRPY -> multiple reply request,
			 REQ_M_USM -> request with no expected reply)
	request_id	returned ID of this request  (A value of zero is
			returned if the request is for an UnSolicited
			Message (USM).)

	This function returns ACNET status values as follows:

	OK			success
	CLIB_INVARG		odd reply length passed
	ACNET_NOSUCH		not connected with this task name
	ACNET_xxx		failed

	This function requires the following include files:

	acnet_h, nodedefs_h, acnet_errors.h
