int PL_get_pointer(term_t +t, void **ptr)
In the current system, pointers are represented by Prolog integers, but need some manipulation to make sure they do not get truncated due to the limited Prolog integer range. PL_put_pointer() and PL_get_pointer() guarantee pointers in the range of malloc() are handled without truncating.
