129 original intent was that I32 be *exactly* 32 bits.
130
131 Currently, we only guarantee that I32 is *at least* 32 bits.
132 Specifically, if int is 64 bits, then so is I32. (This is the case
133 for the Cray.) This has the advantage of meshing nicely with
134 standard library calls (where we pass an I32 and the library is
135 expecting an int), but the disadvantage that an I32 is not 32 bits.
136 Andy Dougherty August 1996
24fef2a7 137
dc45a647 138 There is no guarantee that there is *any* integral type with
139 exactly 32 bits. It is perfectly legal for a system to have
140 sizeof(short) == sizeof(int) == sizeof(long) == 8.
693762b4 141
dc45a647 142 Similarly, there is no guarantee that I16 and U16 have exactly 16
143 bits.
693762b4 144

954c1994 648The XSUB-writer's interface to the C C<malloc> function.
649
c5008215 650In 5.9.3, Newx() and friends replace the older New() API, and drops
651the first parameter, I<x>, a debug aid which allowed callers to identify
37b8b4c9 652themselves. This aid has been superseded by a new build option,
c5008215 653PERL_MEM_LOG (see L<perlhack/PERL_MEM_LOG>). The older API is still
654there for use in XS modules supporting older perls.

9f653bb5 756 * If PERL_MEM_LOG is defined, all Newx()s, Renew()s, and Safefree()s
46c6c7e2 757 * go through functions, which are handy for debugging breakpoints, but
758 * which more importantly get the immediate calling environment (file and
e352bcff 759 * line number, and C function name if available) passed in. This info can
760 * then be used for logging the calls, for which one gets a sample
73d1d973 761 * implementation unless -DPERL_MEM_LOG_NOIMPL is also defined.
3609ea0d 762 *
46c6c7e2 763 * Known problems:
764 * - all memory allocs do not get logged, only those
765 * that go through Newx() and derivatives (while all
766 * Safefrees do get logged)
767 * - __FILE__ and __LINE__ do not work everywhere
768 * - __func__ or __FUNCTION__ even less so
769 * - I think more goes on after the perlio frees but
770 * the thing is that STDERR gets closed (as do all
771 * the file descriptors)
772 * - no deeper calling stack than the caller of the Newx()
773 * or the kind, but do I look like a C reflection/introspection
774 * utility to you?
775 * - the function prototypes for the logging functions
776 * probably should maybe be somewhere else than handy.h
777 * - one could consider inlining (macrofying) the logging
778 * for speed, but I am too lazy
779 * - one could imagine recording the allocations in a hash,
780 * (keyed by the allocation address?), and maintain that
781 * through reallocs and frees, but how to do that without
782 * any News() happening...?
73d1d973 783 * - lots of -Ddefines to get useful/controllable output
b953482e 784 * - lots of ENV reads
