/**************************************************************

* 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
* Brian Stafford <brian@stafford.uklinux.net> 2002/01/28
42
* Removed calls to va_arg(ap, [unsigned] short); etc. This is because
43
* shorts are promoted to int when passed in a ... function argument and
44
* should be referred to as va_arg(ap, [unsigned] int); Added const to
45
* string argument types - snprintf does not modify the strings.
