* Original:
11
* Patrick Powell Tue Apr 11 09:48:21 PDT 1995
12
* A bombproof version of doprnt (dopr) included.
13
* Sigh. This sort of thing is always nasty do deal with. Note that
14
* the version here does not include floating point...
15
*
16
* snprintf() is used instead of sprintf() as it does limit checks
17
* for string length. This covers a nasty loophole.
18
*
19
* The other functions are there to prevent NULL pointers from
20
* causing nast effects.
21
*
22
* More Recently:
23
* Brandon Long <blong@fiction.net> 9/15/96 for mutt 0.43
24
* This was ugly. It is still ugly. I opted out of floating point
25
* numbers, but the formatter understands just about everything
26
* from the normal C string format, at least as far as I can tell from
27
* the Solaris 2.5 printf(3S) man page.
28
*
29
* Brandon Long <blong@fiction.net> 10/22/97 for mutt 0.87.1
30
* Ok, added some minimal floating point support, which means this
31
* probably requires libm on most operating systems. Don't yet
32
* support the exponent (e,E) and sigfig (g,G). Also, fmtint()
33
* was pretty badly broken, it just wasn't being exercised in ways
34
* which showed it, so that's been fixed. Also, formated the code
35
* to mutt conventions, and removed dead code left over from the
36
* original. Also, there is now a builtin-test, just compile with:
37
* gcc -DTEST_SNPRINTF -o snprintf snprintf.c -lm
38
* and run snprintf for results.
39
*
40
* Thomas Roessler <roessler@guug.de> 01/27/98 for mutt 0.89i
41
* The PGP code was using unsigned hexadecimal formats.
42
* Unfortunately, unsigned formats simply didn't work.
43
*
44
* Michael Elkins <me@cs.hmc.edu> 03/05/98 for mutt 0.90.8
45
* The original code assumed that both snprintf() and vsnprintf() were
46
* missing. Some systems only have snprintf() but not vsnprintf(), so
47
* the code is now broken down under HAVE_SNPRINTF and HAVE_VSNPRINTF.
48
*
49
* Andrew Tridgell (tridge@samba.org) Oct 1998
50
* fixed handling of %.0f
51
* added test for HAVE_LONG_DOUBLE
52
*
