115 original intent was that I32 be *exactly* 32 bits.
116
117 Currently, we only guarantee that I32 is *at least* 32 bits.
118 Specifically, if int is 64 bits, then so is I32. (This is the case
119 for the Cray.) This has the advantage of meshing nicely with
120 standard library calls (where we pass an I32 and the library is
121 expecting an int), but the disadvantage that an I32 is not 32 bits.
122 Andy Dougherty August 1996
24fef2a7 123
dc45a647 124 There is no guarantee that there is *any* integral type with
125 exactly 32 bits. It is perfectly legal for a system to have
126 sizeof(short) == sizeof(int) == sizeof(long) == 8.
693762b4 127
dc45a647 128 Similarly, there is no guarantee that I16 and U16 have exactly 16
129 bits.
693762b4 130
8e84507e 131 For dealing with issues that may arise from various 32/64-bit
132 systems, we will ask Configure to check out

636
c5008215 637In 5.9.3, Newx() and friends replace the older New() API, and drops
638the first parameter, I<x>, a debug aid which allowed callers to identify
37b8b4c9 639themselves. This aid has been superseded by a new build option,
c5008215 640PERL_MEM_LOG (see L<perlhack/PERL_MEM_LOG>). The older API is still

46c6c7e2 744 * go through functions, which are handy for debugging breakpoints, but
745 * which more importantly get the immediate calling environment (file and
e352bcff 746 * line number, and C function name if available) passed in. This info can
747 * then be used for logging the calls, for which one gets a sample
748 * implementation if PERL_MEM_LOG_STDERR is defined.
3609ea0d 749 *
46c6c7e2 750 * Known problems:
751 * - all memory allocs do not get logged, only those
752 * that go through Newx() and derivatives (while all
753 * Safefrees do get logged)
754 * - __FILE__ and __LINE__ do not work everywhere
755 * - __func__ or __FUNCTION__ even less so
756 * - I think more goes on after the perlio frees but
757 * the thing is that STDERR gets closed (as do all
758 * the file descriptors)
759 * - no deeper calling stack than the caller of the Newx()
760 * or the kind, but do I look like a C reflection/introspection
761 * utility to you?
762 * - the function prototypes for the logging functions
763 * probably should maybe be somewhere else than handy.h
764 * - one could consider inlining (macrofying) the logging
765 * for speed, but I am too lazy
766 * - one could imagine recording the allocations in a hash,
767 * (keyed by the allocation address?), and maintain that
768 * through reallocs and frees, but how to do that without
769 * any News() happening...?
