/* 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).

Creates a new SV. A non-zero C<len> parameter indicates the number of
bytes of preallocated string space the SV should have. An extra byte for a
tailing NUL is also reserved. (SvPOK is not set for the SV even if string
space is allocated.) The reference count for the new SV is set to 1.
C<id> is an integer id between 0 and 1299 (used to identify leaks).
=for apidoc Am|void|New|int id|void* ptr|int nitems|type
The XSUB-writer's interface to the C C<malloc> function.

The XSUB-writer's interface to the C C<malloc> function, with
cast.
=for apidoc Am|void|Newz|int id|void* ptr|int nitems|type
The XSUB-writer's interface to the C C<malloc> function. The allocated
memory is zeroed with C<memzero>.
=for apidoc Am|void|Renew|void* ptr|int nitems|type
The XSUB-writer's interface to the C C<realloc> function.

The XSUB-writer's interface to the C C<realloc> function, with

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|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|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|StructCopy|type src|type dest|type
