2 * Original:
3 * Patrick Powell Tue Apr 11 09:48:21 PDT 1995
4 * A bombproof version of doprnt (dopr) included.
5 * Sigh. This sort of thing is always nasty do deal with. Note that
6 * the version here does not include floating point...
7 *
8 * snprintf() is used instead of sprintf() as it does limit checks
9 * for string length. This covers a nasty loophole.
10 *
11 * The other functions are there to prevent NULL pointers from
12 * causing nast effects.
13 *
14 * More Recently:
15 * Brandon Long <blong@fiction.net> 9/15/96 for mutt 0.43
16 * This was ugly. It is still ugly. I opted out of floating point
17 * numbers, but the formatter understands just about everything
18 * from the normal C string format, at least as far as I can tell from
19 * the Solaris 2.5 printf(3S) man page.
20 *
21 * Brandon Long <blong@fiction.net> 10/22/97 for mutt 0.87.1
22 * Ok, added some minimal floating point support, which means this
23 * probably requires libm on most operating systems. Don't yet
24 * support the exponent (e,E) and sigfig (g,G). Also, fmtint()
25 * was pretty badly broken, it just wasn't being exercised in ways
26 * which showed it, so that's been fixed. Also, formated the code
27 * to mutt conventions, and removed dead code left over from the
28 * original. Also, there is now a builtin-test, just compile with:
29 * gcc -DTEST_SNPRINTF -o snprintf snprintf.c -lm
30 * and run snprintf for results.
31 *
32 * Thomas Roessler <roessler@guug.de> 01/27/98 for mutt 0.89i
33 * The PGP code was using unsigned hexadecimal formats.
34 * Unfortunately, unsigned formats simply didn't work.
35 *
36 * Michael Elkins <me@cs.hmc.edu> 03/05/98 for mutt 0.90.8
37 * The original code assumed that both snprintf() and vsnprintf() were
38 * missing. Some systems only have snprintf() but not vsnprintf(), so
39 * the code is now broken down under HAVE_SNPRINTF and HAVE_VSNPRINTF.
40 *
41 * Ben Lindstrom <mouring@pconline.com> 09/27/00 for OpenSSH
42 * Welcome to the world of %lld and %qd support. With other
43 * long long support. This is needed for sftp-server to work
44 * right.
