120 original intent was that I32 be *exactly* 32 bits.
121
122 Currently, we only guarantee that I32 is *at least* 32 bits.
123 Specifically, if int is 64 bits, then so is I32. (This is the case
124 for the Cray.) This has the advantage of meshing nicely with
125 standard library calls (where we pass an I32 and the library is
126 expecting an int), but the disadvantage that an I32 is not 32 bits.
127 Andy Dougherty August 1996
24fef2a7 128
dc45a647 129 There is no guarantee that there is *any* integral type with
130 exactly 32 bits. It is perfectly legal for a system to have
131 sizeof(short) == sizeof(int) == sizeof(long) == 8.
693762b4 132
dc45a647 133 Similarly, there is no guarantee that I16 and U16 have exactly 16
134 bits.
693762b4 135
8e84507e 136 For dealing with issues that may arise from various 32/64-bit
137 systems, we will ask Configure to check out

643the first parameter, I<x>, a debug aid which allowed callers to identify
37b8b4c9 644themselves. This aid has been superseded by a new build option,
c5008215 645PERL_MEM_LOG (see L<perlhack/PERL_MEM_LOG>). The older API is still

46c6c7e2 747/*
9f653bb5 748 * If PERL_MEM_LOG is defined, all Newx()s, Renew()s, and Safefree()s
46c6c7e2 749 * go through functions, which are handy for debugging breakpoints, but
750 * which more importantly get the immediate calling environment (file and
e352bcff 751 * line number, and C function name if available) passed in. This info can
752 * then be used for logging the calls, for which one gets a sample
753 * implementation if PERL_MEM_LOG_STDERR is defined.
3609ea0d 754 *
46c6c7e2 755 * Known problems:
756 * - all memory allocs do not get logged, only those
757 * that go through Newx() and derivatives (while all
758 * Safefrees do get logged)
759 * - __FILE__ and __LINE__ do not work everywhere
760 * - __func__ or __FUNCTION__ even less so
761 * - I think more goes on after the perlio frees but
762 * the thing is that STDERR gets closed (as do all
763 * the file descriptors)
764 * - no deeper calling stack than the caller of the Newx()
765 * or the kind, but do I look like a C reflection/introspection
766 * utility to you?
767 * - the function prototypes for the logging functions
768 * probably should maybe be somewhere else than handy.h
769 * - one could consider inlining (macrofying) the logging
770 * for speed, but I am too lazy
771 * - one could imagine recording the allocations in a hash,
772 * (keyed by the allocation address?), and maintain that
773 * through reallocs and frees, but how to do that without
774 * any News() happening...?
