- * 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
|
|
|
|
|
- *
|
|
|
|
|
- * Fabian Knittel <fknittel@gmx.de> Apr 2000 for eggdrop 1.5.3
|
|
|
|
|
- * Indented code to match eggdrop style. Adjusted to fit into eggdrops
|
|
|
|
|
- * build environment. Added `egg_' prefixes to snprintf and vsnprintf.

|

|
|
|
+ * 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
|
|
|
|
|
+ *
|
|
|
|
|
+ * Fabian Knittel <fknittel@gmx.de> Apr 2000 for eggdrop 1.5.3
|
|
|
|
|
+ * Indented code to match eggdrop style. Adjusted to fit into eggdrops
|
|
|
|
|
+ * build environment. Added `egg_' prefixes to snprintf and vsnprintf.
