Safe method for getting the targ member variable.

This performs extra checks to ensure that ReferenceTarget pointer ParamBlockPLCB::targ is still valid and hasn't been deleted. Therefore, do not access the targ member variable in class ParamBlockPLCB directly but rather use this method.

Returns:

Returns targ if the ReferenceTarget pointer is still valid, otherwise NULL.
