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

c5008215 638In 5.9.3, Newx() and friends replace the older New() API, and drops
639the first parameter, I<x>, a debug aid which allowed callers to identify
37b8b4c9 640themselves. This aid has been superseded by a new build option,
c5008215 641PERL_MEM_LOG (see L<perlhack/PERL_MEM_LOG>). The older API is still

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