109
110 Currently, we only guarantee that I32 is *at least* 32 bits.
111 Specifically, if int is 64 bits, then so is I32. (This is the case
112 for the Cray.) This has the advantage of meshing nicely with
113 standard library calls (where we pass an I32 and the library is
114 expecting an int), but the disadvantage that an I32 is not 32 bits.

9f653bb5 728 * If PERL_MEM_LOG is defined, all Newx()s, Renew()s, and Safefree()s
46c6c7e2
JH		 729 * go through functions, which are handy for debugging breakpoints, but
730 * which more importantly get the immediate calling environment (file and
e352bcff
JH		 731 * line number, and C function name if available) passed in. This info can
732 * then be used for logging the calls, for which one gets a sample
733 * implementation if PERL_MEM_LOG_STDERR is defined.
3609ea0d 734 *
46c6c7e2
JH		 735 * Known problems:
736 * - all memory allocs do not get logged, only those
737 * that go through Newx() and derivatives (while all
738 * Safefrees do get logged)
739 * - __FILE__ and __LINE__ do not work everywhere
740 * - __func__ or __FUNCTION__ even less so
741 * - I think more goes on after the perlio frees but
742 * the thing is that STDERR gets closed (as do all
743 * the file descriptors)
744 * - no deeper calling stack than the caller of the Newx()
745 * or the kind, but do I look like a C reflection/introspection
746 * utility to you?
747 * - the function prototypes for the logging functions
748 * probably should maybe be somewhere else than handy.h
749 * - one could consider inlining (macrofying) the logging
750 * for speed, but I am too lazy
751 * - one could imagine recording the allocations in a hash,
752 * (keyed by the allocation address?), and maintain that
753 * through reallocs and frees, but how to do that without
754 * any News() happening...?
