status.i4.v = dio_delete_pdb_lst(list_id.i4.r [,errors.i2a.r])
	This function removes PDBs (and DI/PI entries), associated with a list,
	from the cached DIO scaling database.  These must have been previously
	entered with a call to "dio_bld_XXX" returning the list id "list_id".

	list_id		list ID returned from "dio_bld_XXX"
	[errors]	error flag for each device in the list
			(TRUE -> device not removed (not in pool),
			 FALSE -> device removed)
			(default is not to return status for each device (NULL))

	This function returns status values as follows:

	OK			success
	DIO_NOLIST		list doesn't exist
	positive value		number of devices in error

	This function requires the following include files:

	cnsparam_h, diolib_h, acnet_errors_h

	Related functions:

	dio_delete_pdb, dio_delete_pdb_all, dio_delete_cache, dio_bld_get(_c),
	dio_bld_set(_c), dio_get_pdb

	C/C++ usage:

	short	errors[NUM_DEVICES];
	int	status;
	int	list_id;

	status = dio_delete_pdb_lst(&list_id,errors);
