This sort of thing is always nasty do deal with. Note that - * the version here does not include floating point... - * - * snprintf() is used instead of sprintf() as it does limit checks - * for string length. This covers a nasty loophole. - * - * The other functions are there to prevent NULL pointers from - * causing nast effects. - * - * More Recently: - * Brandon Long 9/15/96 for mutt 0.43 - * This was ugly. It is still ugly. I opted out of floating point - * numbers, but the formatter understands just about everything - * from the normal C string format, at least as far as I can tell from - * the Solaris 2.5 printf(3S) man page. - * - * Brandon Long 10/22/97 for mutt 0.87.1 - * Ok, added some minimal floating point support, which means this - * probably requires libm on most operating systems. Don't yet - * support the exponent (e,E) and sigfig (g,G). Also, fmtint() - * was pretty badly broken, it just wasn't being exercised in ways - * which showed it, so that's been fixed. Also, formated the code - * to mutt conventions, and removed dead code left over from the - * original. Also, there is now a builtin-test, just compile with: - * gcc -DTEST_SNPRINTF -o snprintf snprintf.c -lm - * and run snprintf for results. - * - * Thomas Roessler 01/27/98 for mutt 0.89i - * The PGP code was using unsigned hexadecimal formats. - * Unfortunately, unsigned formats simply didn't work. - * - * Michael Elkins 03/05/98 for mutt 0.90.8 - * The original code assumed that both snprintf() and vsnprintf() were - * missing. Some systems only have snprintf() but not vsnprintf(), so - * the code is now broken down under HAVE_SNPRINTF and HAVE_VSNPRINTF. - * - * Andrew Tridgell (tridge@samba.org) Oct 1998 - * fixed handling of %.0f - * added test for HAVE_LONG_DOUBLE - * - * Russ Allbery 2000-08-26 - * fixed return value to comply with C99 - * fixed handling of snprintf(NULL, ...) - * - * Hrvoje Niksic 2000-11-04 - * include instead of "config.h". - * moved TEST_SNPRINTF stuff out of HAVE_SNPRINTF ifdef. - * include for NULL. - * added support and test cases for long long. - * don't declare argument types to (v)snprintf if stdarg is not used. - * use int instead of short int as 2nd arg to va_arg. - * - **************************************************************/ - -/* BDR 2002-01-13 %e and %g were being ignored.
