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 505 XXX LEAKTEST doesn't really work in perl5. There are direct calls to
27d4fb96 506 safemalloc() in the source, so LEAKTEST won't pick them up.
c1d22f6b 507 (The main "offenders" are extensions.)
27d4fb96 508 Further, if you try LEAKTEST, you'll also end up calling
509 Safefree, which might call safexfree() on some things that weren't
510 malloced with safexmalloc. The correct "fix" to this, if anyone
511 is interested, is to ensure that all calls go through the New and
512 Renew macros.

517=for apidoc Am|SV*|NEWSV|int id|STRLEN len
518Creates a new SV. A non-zero C<len> parameter indicates the number of
519bytes of preallocated string space the SV should have. An extra byte for a
520tailing NUL is also reserved. (SvPOK is not set for the SV even if string
8e84507e 521space is allocated.) The reference count for the new SV is set to 1.
954c1994 522C<id> is an integer id between 0 and 1299 (used to identify leaks).
523
524=for apidoc Am|void|New|int id|void* ptr|int nitems|type
525The XSUB-writer's interface to the C C<malloc> function.
526
527=for apidoc Am|void|Newc|int id|void* ptr|int nitems|type|cast
528The XSUB-writer's interface to the C C<malloc> function, with
529cast.
530
531=for apidoc Am|void|Newz|int id|void* ptr|int nitems|type
532The XSUB-writer's interface to the C C<malloc> function. The allocated
533memory is zeroed with C<memzero>.
534
535=for apidoc Am|void|Renew|void* ptr|int nitems|type
536The XSUB-writer's interface to the C C<realloc> function.
537
538=for apidoc Am|void|Renewc|void* ptr|int nitems|type|cast
539The XSUB-writer's interface to the C C<realloc> function, with
540cast.
541
49b8b560 542=for apidoc Am|void|Safefree|void* ptr
954c1994 543The XSUB-writer's interface to the C C<free> function.
544
545=for apidoc Am|void|Move|void* src|void* dest|int nitems|type
546The XSUB-writer's interface to the C C<memmove> function. The C<src> is the
547source, C<dest> is the destination, C<nitems> is the number of items, and C<type> is
548the type. Can do overlapping moves. See also C<Copy>.
549
550=for apidoc Am|void|Copy|void* src|void* dest|int nitems|type
551The XSUB-writer's interface to the C C<memcpy> function. The C<src> is the
552source, C<dest> is the destination, C<nitems> is the number of items, and C<type> is
553the type. May fail on overlapping copies. See also C<Move>.
554
555=for apidoc Am|void|Zero|void* dest|int nitems|type
556
557The XSUB-writer's interface to the C C<memzero> function. The C<dest> is the
558destination, C<nitems> is the number of items, and C<type> is the type.
559
