/* 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).

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

=for apidoc Am|SV*|NEWSV|int id|STRLEN len
|
|
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.
|
|
|
|
=for apidoc Am|void|Newc|int id|void* ptr|int nitems|type|cast
|

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.
|
|

|
=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|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
|

This is an architecture-independent macro to copy one structure to another.
