- /* XXX A note on the perl source internal type system. The
- original intent was that I32 be *exactly* 32 bits.
-
- Currently, we only guarantee that I32 is *at least* 32 bits.
- Specifically, if int is 64 bits, then so is I32. (This is the case
- for the Cray.) This has the advantage of meshing nicely with
- standard library calls (where we pass an I32 and the library is
- expecting an int), but the disadvantage that an I32 is not 32 bits.
- Andy Dougherty August 1996
-
- There is no guarantee that there is *any* integral type with
- exactly 32 bits. It is perfectly legal for a system to have
- sizeof(short) == sizeof(int) == sizeof(long) == 8.
-
- Similarly, there is no guarantee that I16 and U16 have exactly 16
- bits.
-
- For dealing with issues that may arise from various 32/64-bit
- systems, we will ask Configure to check out
-
- SHORTSIZE == sizeof(short)
- INTSIZE == sizeof(int)
- LONGSIZE == sizeof(long)
- LONGLONGSIZE == sizeof(long long) (if HAS_LONG_LONG)
- PTRSIZE == sizeof(void *)
- DOUBLESIZE == sizeof(double)
- LONG_DOUBLESIZE == sizeof(long double) (if HAS_LONG_DOUBLE).

-
- =for apidoc Am|void|Newx|void* ptr|int nitems|type
- The XSUB-writer's interface to the C C<malloc> function.
-
- In 5.9.3, Newx() and friends replace the older New() API, and drops
- the first parameter, I<x>, a debug aid which allowed callers to identify
- themselves. This aid has been superseded by a new build option,
- PERL_MEM_LOG (see L<perlhack/PERL_MEM_LOG>). The older API is still
- there for use in XS modules supporting older perls.
-
- =for apidoc Am|void|Newxc|void* ptr|int nitems|type|cast
- The XSUB-writer's interface to the C C<malloc> function, with
- cast. See also C<Newx>.
-
- =for apidoc Am|void|Newxz|void* ptr|int nitems|type
- The XSUB-writer's interface to the C C<malloc> function. The allocated
- memory is zeroed with C<memzero>. See also C<Newx>.
-
- =for apidoc Am|void|Renew|void* ptr|int nitems|type
- The XSUB-writer's interface to the C C<realloc> function.
-
- =for apidoc Am|void|Renewc|void* ptr|int nitems|type|cast
- The XSUB-writer's interface to the C C<realloc> function, with
- cast.
-
- =for apidoc Am|void|Safefree|void* ptr
- The XSUB-writer's interface to the C C<free> function.
-
- =for apidoc Am|void|Move|void* src|void* dest|int nitems|type
- The XSUB-writer's interface to the C C<memmove> function. The C<src> is the
- source, C<dest> is the destination, C<nitems> is the number of items, and C<type> is
- the type. Can do overlapping moves. See also C<Copy>.
-
- =for apidoc Am|void *|MoveD|void* src|void* dest|int nitems|type
- Like C<Move> but returns dest. Useful for encouraging compilers to tail-call
- optimise.
-
- =for apidoc Am|void|Copy|void* src|void* dest|int nitems|type
- The XSUB-writer's interface to the C C<memcpy> function. The C<src> is the
- source, C<dest> is the destination, C<nitems> is the number of items, and C<type> is
- the type. May fail on overlapping copies. See also C<Move>.
-
- =for apidoc Am|void *|CopyD|void* src|void* dest|int nitems|type
-
- Like C<Copy> but returns dest. Useful for encouraging compilers to tail-call
- optimise.
-
- =for apidoc Am|void|Zero|void* dest|int nitems|type
-
- The XSUB-writer's interface to the C C<memzero> function. The C<dest> is the
- destination, C<nitems> is the number of items, and C<type> is the type.
-
- =for apidoc Am|void *|ZeroD|void* dest|int nitems|type
-
- Like C<Zero> but returns dest. Useful for encouraging compilers to tail-call
- optimise.
-
- =for apidoc Am|void|StructCopy|type src|type dest|type
- This is an architecture-independent macro to copy one structure to another.
-
- =for apidoc Am|void|PoisonWith|void* dest|int nitems|type|U8 byte
-
- Fill up memory with a byte pattern (a byte repeated over and over
- again) that hopefully catches attempts to access uninitialized memory.
-
- =for apidoc Am|void|PoisonNew|void* dest|int nitems|type
-
- PoisonWith(0xAB) for catching access to allocated but uninitialized memory.
-
- =for apidoc Am|void|PoisonFree|void* dest|int nitems|type
-
- PoisonWith(0xEF) for catching access to freed memory.
-
- =for apidoc Am|void|Poison|void* dest|int nitems|type
