27d4fb96 90/* XXX A note on the perl source internal type system. The
91 original intent was that I32 be *exactly* 32 bits.
92
93 Currently, we only guarantee that I32 is *at least* 32 bits.
94 Specifically, if int is 64 bits, then so is I32. (This is the case
95 for the Cray.) This has the advantage of meshing nicely with
96 standard library calls (where we pass an I32 and the library is
97 expecting an int), but the disadvantage that an I32 is not 32 bits.
98 Andy Dougherty August 1996
24fef2a7 99
dc45a647 100 There is no guarantee that there is *any* integral type with
101 exactly 32 bits. It is perfectly legal for a system to have
102 sizeof(short) == sizeof(int) == sizeof(long) == 8.
693762b4 103
dc45a647 104 Similarly, there is no guarantee that I16 and U16 have exactly 16
105 bits.
693762b4 106
8e84507e 107 For dealing with issues that may arise from various 32/64-bit
108 systems, we will ask Configure to check out

531
954c1994 532=for apidoc Am|SV*|NEWSV|int id|STRLEN len
533Creates a new SV. A non-zero C<len> parameter indicates the number of
534bytes of preallocated string space the SV should have. An extra byte for a
535tailing NUL is also reserved. (SvPOK is not set for the SV even if string
8e84507e 536space is allocated.) The reference count for the new SV is set to 1.
954c1994 537C<id> is an integer id between 0 and 1299 (used to identify leaks).

ccfc67b7 539=head1 Memory Management
540
954c1994 541=for apidoc Am|void|New|int id|void* ptr|int nitems|type
542The XSUB-writer's interface to the C C<malloc> function.
543
544=for apidoc Am|void|Newc|int id|void* ptr|int nitems|type|cast
545The XSUB-writer's interface to the C C<malloc> function, with
546cast.
547
548=for apidoc Am|void|Newz|int id|void* ptr|int nitems|type
549The XSUB-writer's interface to the C C<malloc> function. The allocated
550memory is zeroed with C<memzero>.
551
552=for apidoc Am|void|Renew|void* ptr|int nitems|type
553The XSUB-writer's interface to the C C<realloc> function.
554
555=for apidoc Am|void|Renewc|void* ptr|int nitems|type|cast
556The XSUB-writer's interface to the C C<realloc> function, with
557cast.
558
49b8b560 559=for apidoc Am|void|Safefree|void* ptr
954c1994 560The XSUB-writer's interface to the C C<free> function.
561
562=for apidoc Am|void|Move|void* src|void* dest|int nitems|type
563The XSUB-writer's interface to the C C<memmove> function. The C<src> is the
564source, C<dest> is the destination, C<nitems> is the number of items, and C<type> is
565the type. Can do overlapping moves. See also C<Copy>.
566
e90e2364 567=for apidoc Am|void *|MoveD|void* src|void* dest|int nitems|type
568Like C<Move> but returns dest. Useful for encouraging compilers to tail-call
569optimise.
570
954c1994 571=for apidoc Am|void|Copy|void* src|void* dest|int nitems|type
572The XSUB-writer's interface to the C C<memcpy> function. The C<src> is the
573source, C<dest> is the destination, C<nitems> is the number of items, and C<type> is
574the type. May fail on overlapping copies. See also C<Move>.
575
e90e2364 576=for apidoc Am|void *|CopyD|void* src|void* dest|int nitems|type
577
578Like C<Copy> but returns dest. Useful for encouraging compilers to tail-call
579optimise.
580
954c1994 581=for apidoc Am|void|Zero|void* dest|int nitems|type
582
583The XSUB-writer's interface to the C C<memzero> function. The C<dest> is the
584destination, C<nitems> is the number of items, and C<type> is the type.
585
e90e2364 586=for apidoc Am|void *|ZeroD|void* dest|int nitems|type
587
588Like C<Zero> but returns dest. Useful for encouraging compilers to tail-call
589optimise.
590
954c1994 591=for apidoc Am|void|StructCopy|type src|type dest|type
4375e838 592This is an architecture-independent macro to copy one structure to another.
954c1994 593
9965345d 594=for apidoc Am|void|Poison|void* dest|int nitems|type
595
596Fill up memory with a pattern (byte 0xAB over and over again) that
597hopefully catches attempts to access uninitialized memory.
