dio_gas_module_devices_c

	status.i4.v = dio_gas_module_devices_c(node.i4.v, house.i4.v,
					       gas_slot.i4.v,
					       num_devices.i4.r,
					       device_indices.i4p.r)

	This routine returns the list of ACNET devices belonging to a
	GAS module type.  Memory for the returned data arrays is allocated
	by this routine and should NOT be freed by the caller.

	node		desired node (constants are in 'nodedefs')
	house		desired house (1-42)
	gas_slot	desired GAS slot (0-6)
	num_devices	returned number of devices
	device_indices	returned device indices
			(A value of NULL may be passed if no device indices
			 are needed.)

	This function returns status values as follows:

	OK			success
	DIO_BADARG		invalid number of devices
	DIO_MEMFAIL		memory allocation failure
	negative value		ACNET format error indicating overall failure

	This function requires the following include files:

	dbprops_h, ul_cbsaux_h:auxlib_device_h, acnet_errors_h

	C/C++ usage:

	int	status;
	int	node = TEV;
	int	house = 1;
	int	gas_slot = 0;
	int	num_devices;
	int	*device_indices;

	status = dio_gas_module_devices_c(node,house,gas_slot,&num_devices,
					  &device_indices);
