27d4fb96 87/* XXX A note on the perl source internal type system. The
88 original intent was that I32 be *exactly* 32 bits.
89
90 Currently, we only guarantee that I32 is *at least* 32 bits.
91 Specifically, if int is 64 bits, then so is I32. (This is the case
92 for the Cray.) This has the advantage of meshing nicely with
93 standard library calls (where we pass an I32 and the library is
94 expecting an int), but the disadvantage that an I32 is not 32 bits.
95 Andy Dougherty August 1996
24fef2a7 96
dc45a647 97 There is no guarantee that there is *any* integral type with
98 exactly 32 bits. It is perfectly legal for a system to have
99 sizeof(short) == sizeof(int) == sizeof(long) == 8.
693762b4 100
dc45a647 101 Similarly, there is no guarantee that I16 and U16 have exactly 16
102 bits.
693762b4 103
8e84507e 104 For dealing with issues that may arise from various 32/64-bit
105 systems, we will ask Configure to check out

8c52afec 511 XXX LEAKTEST doesn't really work in perl5. There are direct calls to
27d4fb96 512 safemalloc() in the source, so LEAKTEST won't pick them up.
c1d22f6b 513 (The main "offenders" are extensions.)
27d4fb96 514 Further, if you try LEAKTEST, you'll also end up calling
515 Safefree, which might call safexfree() on some things that weren't
516 malloced with safexmalloc. The correct "fix" to this, if anyone
517 is interested, is to ensure that all calls go through the New and
518 Renew macros.

523=for apidoc Am|SV*|NEWSV|int id|STRLEN len
524Creates a new SV. A non-zero C<len> parameter indicates the number of
525bytes of preallocated string space the SV should have. An extra byte for a
526tailing NUL is also reserved. (SvPOK is not set for the SV even if string
8e84507e 527space is allocated.) The reference count for the new SV is set to 1.
954c1994 528C<id> is an integer id between 0 and 1299 (used to identify leaks).
529
530=for apidoc Am|void|New|int id|void* ptr|int nitems|type
531The XSUB-writer's interface to the C C<malloc> function.
532
533=for apidoc Am|void|Newc|int id|void* ptr|int nitems|type|cast
534The XSUB-writer's interface to the C C<malloc> function, with
535cast.
536
537=for apidoc Am|void|Newz|int id|void* ptr|int nitems|type
538The XSUB-writer's interface to the C C<malloc> function. The allocated
539memory is zeroed with C<memzero>.
540
541=for apidoc Am|void|Renew|void* ptr|int nitems|type
542The XSUB-writer's interface to the C C<realloc> function.
543
544=for apidoc Am|void|Renewc|void* ptr|int nitems|type|cast
545The XSUB-writer's interface to the C C<realloc> function, with
546cast.
547
49b8b560 548=for apidoc Am|void|Safefree|void* ptr
954c1994 549The XSUB-writer's interface to the C C<free> function.
550
551=for apidoc Am|void|Move|void* src|void* dest|int nitems|type
552The XSUB-writer's interface to the C C<memmove> function. The C<src> is the
553source, C<dest> is the destination, C<nitems> is the number of items, and C<type> is
554the type. Can do overlapping moves. See also C<Copy>.
555
556=for apidoc Am|void|Copy|void* src|void* dest|int nitems|type
557The XSUB-writer's interface to the C C<memcpy> function. The C<src> is the
558source, C<dest> is the destination, C<nitems> is the number of items, and C<type> is
559the type. May fail on overlapping copies. See also C<Move>.
560
561=for apidoc Am|void|Zero|void* dest|int nitems|type
562
563The XSUB-writer's interface to the C C<memzero> function. The C<dest> is the
564destination, C<nitems> is the number of items, and C<type> is the type.
565
