get_453_channel

	status.i4.v = get_453_channel(device_indices.i4a.r, channels.i4a.r,
				      errors.i2a.r [,num_devices.i4.v])

	This routine returns the channel on the C453 card associated with
	this device.

	device_indices	device index or array of indices
	channels	returned channel number (0-3) or array
			of channels
	errors		returned device error or array of errors
	[num_devices]	number of devices (default is 1)

	This function returns ACNET status values as follows:

	OK			success
	CBS_MEMFAIL		dynamic memory allocation failure
	CBS_INVTYP		device is not a C453 module
	DIO_xxx			error retrieving database info

	This function requires the following include files:

	ul_cbsaux_h:auxlib_device_h, acnet_errors_h

	get_453_device, get_453_family

	C/C++ usage:

	short	errors[NUM_DEVICES];
	int	status;
	static const int	device_indices[NUM_DEVICES] = {14438, 14545};
	int	channels[NUM_DEVICES];
	int	num_devices = NUM_DEVICES;

	status = get_453_channel(device_indices,channels,errors,num_devices);
