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

8c52afec 516 XXX LEAKTEST doesn't really work in perl5. There are direct calls to
27d4fb96 517 safemalloc() in the source, so LEAKTEST won't pick them up.
c1d22f6b 518 (The main "offenders" are extensions.)
27d4fb96 519 Further, if you try LEAKTEST, you'll also end up calling
520 Safefree, which might call safexfree() on some things that weren't
521 malloced with safexmalloc. The correct "fix" to this, if anyone
522 is interested, is to ensure that all calls go through the New and
523 Renew macros.

ccfc67b7 528=head1 SV Manipulation Functions
529
954c1994 530=for apidoc Am|SV*|NEWSV|int id|STRLEN len
531Creates a new SV. A non-zero C<len> parameter indicates the number of
532bytes of preallocated string space the SV should have. An extra byte for a
533tailing NUL is also reserved. (SvPOK is not set for the SV even if string
8e84507e 534space is allocated.) The reference count for the new SV is set to 1.
954c1994 535C<id> is an integer id between 0 and 1299 (used to identify leaks).

ccfc67b7 537=head1 Memory Management
538
954c1994 539=for apidoc Am|void|New|int id|void* ptr|int nitems|type
540The XSUB-writer's interface to the C C<malloc> function.
541
542=for apidoc Am|void|Newc|int id|void* ptr|int nitems|type|cast
543The XSUB-writer's interface to the C C<malloc> function, with
544cast.
545
546=for apidoc Am|void|Newz|int id|void* ptr|int nitems|type
547The XSUB-writer's interface to the C C<malloc> function. The allocated
548memory is zeroed with C<memzero>.
549
550=for apidoc Am|void|Renew|void* ptr|int nitems|type
551The XSUB-writer's interface to the C C<realloc> function.
552
553=for apidoc Am|void|Renewc|void* ptr|int nitems|type|cast
554The XSUB-writer's interface to the C C<realloc> function, with
555cast.
556
49b8b560 557=for apidoc Am|void|Safefree|void* ptr
954c1994 558The XSUB-writer's interface to the C C<free> function.
559
560=for apidoc Am|void|Move|void* src|void* dest|int nitems|type
561The XSUB-writer's interface to the C C<memmove> function. The C<src> is the
562source, C<dest> is the destination, C<nitems> is the number of items, and C<type> is
563the type. Can do overlapping moves. See also C<Copy>.
564
565=for apidoc Am|void|Copy|void* src|void* dest|int nitems|type
566The XSUB-writer's interface to the C C<memcpy> function. The C<src> is the
567source, C<dest> is the destination, C<nitems> is the number of items, and C<type> is
568the type. May fail on overlapping copies. See also C<Move>.
569
570=for apidoc Am|void|Zero|void* dest|int nitems|type
571
572The XSUB-writer's interface to the C C<memzero> function. The C<dest> is the
573destination, C<nitems> is the number of items, and C<type> is the type.
574
575=for apidoc Am|void|StructCopy|type src|type dest|type
4375e838 576This is an architecture-independent macro to copy one structure to another.
