status.i4.v = mio_pool_address(num_devices.i4.v, device_indices.i4a.r,
				       properties.i2a.r, raw_data_ptrs.i1pa.r)

	This routine returns addresses of raw data in the MIO datapool.

	num_devices	number of devices requested
	device_indices	device indexes
	properties	property indexes
	raw_data_ptrs	returned addresses of raw data into caller's array
	  		of char pointers (A value of NULL will be returned
			if no pool entry exists.)

	This function returns ACNET status values as follows:

	OK			success
	negative value		overall ACNET error

	This function requires the following include files:

	dbprops_h, diolib_h, acnet_errors_h, tclk_events_h

	Related functions:

	dio_simulate, mio_set, mio_control, mio_cancel, mio_fill_status

	C/C++ usage:

	char	*raw_data_ptrs[NUM_DEVICES];
	short	errors[NUM_DEVICES];
	static const short	properties[NUM_DEVICES] = {PRSET, PRSET};
	int	status;
	int	num_devices = NUM_DEVICES;
	static const int	device_indices[NUM_DEVICES] = {14430, 14431};

	status = mio_pool_address(num_devices,device_indices,properties,
