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@eviladmin.org> 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.
45  *
46  *  Ben Lindstrom <mouring@eviladmin.org> 02/12/01 for OpenSSH
47  *    Removed all hint of VARARGS stuff and banished it to the void,
48  *    and did a bit of KNF style work to make things a bit more
49  *    acceptable.  Consider stealing from mutt or enlightenment.
