| * Original: |
| * Patrick Powell Tue Apr 11 09:48:21 PDT 1995 |
| * A bombproof version of doprnt (dopr) included. |
| * Sigh. 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 <blong@fiction.net> 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 <blong@fiction.net> 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 <roessler@guug.de> 01/27/98 for mutt 0.89i |
| * The PGP code was using unsigned hexadecimal formats. |
| * Unfortunately, unsigned formats simply didn't work. |
| * |
| * Michael Elkins <me@cs.hmc.edu> 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 |
