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
dc45a647 104 For dealing with issues that may arise from various 32/64-bit
105 systems, we will ask Configure to check out

8c52afec 488 XXX LEAKTEST doesn't really work in perl5. There are direct calls to
27d4fb96 489 safemalloc() in the source, so LEAKTEST won't pick them up.
c1d22f6b 490 (The main "offenders" are extensions.)
27d4fb96 491 Further, if you try LEAKTEST, you'll also end up calling
492 Safefree, which might call safexfree() on some things that weren't
493 malloced with safexmalloc. The correct "fix" to this, if anyone
494 is interested, is to ensure that all calls go through the New and
495 Renew macros.

500=for apidoc Am|SV*|NEWSV|int id|STRLEN len
501Creates a new SV. A non-zero C<len> parameter indicates the number of
502bytes of preallocated string space the SV should have. An extra byte for a
503tailing NUL is also reserved. (SvPOK is not set for the SV even if string
504space is allocated.) The reference count for the new SV is set to 1.
505C<id> is an integer id between 0 and 1299 (used to identify leaks).
506
507=for apidoc Am|void|New|int id|void* ptr|int nitems|type
508The XSUB-writer's interface to the C C<malloc> function.
509
510=for apidoc Am|void|Newc|int id|void* ptr|int nitems|type|cast
511The XSUB-writer's interface to the C C<malloc> function, with
512cast.
513
514=for apidoc Am|void|Newz|int id|void* ptr|int nitems|type
515The XSUB-writer's interface to the C C<malloc> function. The allocated
516memory is zeroed with C<memzero>.
517
518=for apidoc Am|void|Renew|void* ptr|int nitems|type
519The XSUB-writer's interface to the C C<realloc> function.
520
521=for apidoc Am|void|Renewc|void* ptr|int nitems|type|cast
522The XSUB-writer's interface to the C C<realloc> function, with
523cast.
524
49b8b560 525=for apidoc Am|void|Safefree|void* ptr
954c1994 526The XSUB-writer's interface to the C C<free> function.
527
528=for apidoc Am|void|Move|void* src|void* dest|int nitems|type
529The XSUB-writer's interface to the C C<memmove> function. The C<src> is the
530source, C<dest> is the destination, C<nitems> is the number of items, and C<type> is
531the type. Can do overlapping moves. See also C<Copy>.
532
533=for apidoc Am|void|Copy|void* src|void* dest|int nitems|type
534The XSUB-writer's interface to the C C<memcpy> function. The C<src> is the
535source, C<dest> is the destination, C<nitems> is the number of items, and C<type> is
536the type. May fail on overlapping copies. See also C<Move>.
537
538=for apidoc Am|void|Zero|void* dest|int nitems|type
539
540The XSUB-writer's interface to the C C<memzero> function. The C<dest> is the
541destination, C<nitems> is the number of items, and C<type> is the type.
542
543=for apidoc Am|void|StructCopy|type src|type dest|type
