status.i4.v = dio_status_attr_bit_mask_c(device_indices.i4a.r,

	This routine returns basic status attributes as a bit mask.

	device_indices	device index or array of device indices
	attr_bit_masks	returned status attribute bit masks
			(Note: This bit mask can be queried using the
			 DIO_STS_MSK_xxx macros.)
	errors		returned ACNET status value or array of returned
			status values (A status of DBM_NOREC indicates that
			no status scaling for that device exists.)
	[num_devices]	number of devices (default is 1)

	This function returns status values as follows:

	OK			success
	DIO_MEMFAIL		memory allocation failure
	negative value		other ACNET format error
	positive value		number of devices in error

	This function requires the following include files:

	cnsparam_h, diolib_h, acnet_errors_h
