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.

MB		 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

8c52afec 471 XXX LEAKTEST doesn't really work in perl5. There are direct calls to
27d4fb96 472 safemalloc() in the source, so LEAKTEST won't pick them up.
c1d22f6b 473 (The main "offenders" are extensions.)
27d4fb96 474 Further, if you try LEAKTEST, you'll also end up calling
475 Safefree, which might call safexfree() on some things that weren't
476 malloced with safexmalloc. The correct "fix" to this, if anyone
477 is interested, is to ensure that all calls go through the New and
478 Renew macros.

483=for apidoc Am|SV*|NEWSV|int id|STRLEN len
484Creates a new SV. A non-zero C<len> parameter indicates the number of
485bytes of preallocated string space the SV should have. An extra byte for a
486tailing NUL is also reserved. (SvPOK is not set for the SV even if string
487space is allocated.) The reference count for the new SV is set to 1.
488C<id> is an integer id between 0 and 1299 (used to identify leaks).
489
490=for apidoc Am|void|New|int id|void* ptr|int nitems|type
491The XSUB-writer's interface to the C C<malloc> function.
492
493=for apidoc Am|void|Newc|int id|void* ptr|int nitems|type|cast
494The XSUB-writer's interface to the C C<malloc> function, with
495cast.
496
497=for apidoc Am|void|Newz|int id|void* ptr|int nitems|type
498The XSUB-writer's interface to the C C<malloc> function. The allocated
499memory is zeroed with C<memzero>.
500
501=for apidoc Am|void|Renew|void* ptr|int nitems|type
502The XSUB-writer's interface to the C C<realloc> function.
503
504=for apidoc Am|void|Renewc|void* ptr|int nitems|type|cast
505The XSUB-writer's interface to the C C<realloc> function, with
506cast.
507
508=for apidoc Am|void|Safefree|void* src|void* dest|int nitems|type
509The XSUB-writer's interface to the C C<free> function.
510
511=for apidoc Am|void|Move|void* src|void* dest|int nitems|type
512The XSUB-writer's interface to the C C<memmove> function. The C<src> is the
513source, C<dest> is the destination, C<nitems> is the number of items, and C<type> is
514the type. Can do overlapping moves. See also C<Copy>.
515
516=for apidoc Am|void|Copy|void* src|void* dest|int nitems|type
517The XSUB-writer's interface to the C C<memcpy> function. The C<src> is the
518source, C<dest> is the destination, C<nitems> is the number of items, and C<type> is
519the type. May fail on overlapping copies. See also C<Move>.
520
521=for apidoc Am|void|Zero|void* dest|int nitems|type
522
523The XSUB-writer's interface to the C C<memzero> function. The C<dest> is the
524destination, C<nitems> is the number of items, and C<type> is the type.
525
526=for apidoc Am|void|StructCopy|type src|type dest|type
527This is an architecture-independant macro to copy one structure to another.
