acnet_request_wait

	status.i4.v = acnet_request_wait(task.i1a.r, dest_node.i2.v,
					 dest_task.i1a.r, request_buffer.g.v,
					 request_length.u4.v, reply_buffer.g.v,
					 reply_length.u4.v, timeout.u2.v,
					 bytes_returned.i4.r)

	This routine sends an ACNET request and waits for a reply or a timeout.

	task		requester ASCII task name (PROCESS_NAME_LEN characters)
			(name used in acnet_connect call)
			(If a value of NULL is passed for this argument,
			 a default connection will be used.)
	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)
	reply_buffer	reply buffer
	reply_length	reply buffer length in bytes (only even lengths allowed)
	timeout		number of milliseconds to wait for a reply
	bytes_returned	returned number of bytes returned  (A value of NULL
			can be passed for this argument if this value is
			not needed.)

	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_UTIME		reply timed out
	ACNET_xxx		request failed

	This function requires the following include files:

	cnsparam_h, acnet_h, nodedefs_h, acnet_errors_h
