638
639 Wrap a user data pointer into a Ptr PMC for passing into Parrot. This PMC
640 is designed such that Parrot will treat the pointer as being opaque and will
641 not attempt to dereference, examine, or manipulate it at all.
642
643 Optionally a C<size> parameter can be passed. If C<size> is greater than zero,
644 the size information will be included with the pointer for later use. If
645 C<size> is less than or equal to zero, it will be ignored and will not be
646 included in the PMC object.

Whiteknight authored
650
651 Return a pointer from a PMC. This is typically used in conjunction with
652 C<Parrot_api_wrap_pointer> to return the original wrapped pointer value from
653 the PMC. Used with other PMC types besides C<Ptr> or C<PtrBuf> will have
654 undefined results, and should not be used or relied upon.
655
656 If the pointer was stored with size information, C<size> will contain that
657 size value. Otherwise, C<size> will be -1.
658
659 Notice that this function does not destroy or alter the data PMC.
