mio_fill_status

	status.i4.v = mio_fill_status(num_devices.i4.v, device_indices.i4a.r,
				      properties.i2a.r, fill_status.i2a.r)

	This routine fills the status for a list of Device Index/Property
	entries in the MIO memory pool.  This does not force population of
	the device/property reading.  It only loads a status for the entry.
	This is the status returned for any reads from the MIO pool.
	This status will remain until a subsequent MIO set on this entry.
	See dio_simulate.

	num_devices	number of devices
	device_indices	device indexes
	properties	property indexes
	fill_status	fill with this device status

	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_read, mio_set, mio_control, mio_cancel

	C/C++ usage:

	static const short	properties[NUM_DEVICES] = {PRSET, PRSET};
	short	fill_status[NUM_DEVICES];
	int	status;
	int	num_devices = NUM_DEVICES;
	static const int	device_indices[NUM_DEVICES] = {14430, 14431};

	status = mio_fill_status(num_devices,device_indices,properties,
				 fill_status);
