* A bombproof version of doprnt (dopr) included.
|
|
Packit |
762fc5 |
* Sigh. This sort of thing is always nasty do deal with. Note that
|
|
Packit |
762fc5 |
* the version here does not include floating point...
|
|
Packit |
762fc5 |
*
|
|
Packit |
762fc5 |
* snprintf() is used instead of sprintf() as it does limit checks
|
|
Packit |
762fc5 |
* for string length. This covers a nasty loophole.
|
|
Packit |
762fc5 |
*
|
|
Packit |
762fc5 |
* The other functions are there to prevent NULL pointers from
|
|
Packit |
762fc5 |
* causing nast effects.

Packit |

* More Recently:
|
|
Packit |
762fc5 |
* Brandon Long <blong@fiction.net> 9/15/96 for mutt 0.43
|
|
Packit |
762fc5 |
* This was ugly. It is still ugly. I opted out of floating point
|
|
Packit |
762fc5 |
* numbers, but the formatter understands just about everything
|
|
Packit |
762fc5 |
* from the normal C string format, at least as far as I can tell from
|
|
Packit |
762fc5 |
* the Solaris 2.5 printf(3S) man page.
|
|
Packit |
762fc5 |
*
|
|
Packit |
762fc5 |
* Brandon Long <blong@fiction.net> 10/22/97 for mutt 0.87.1
|
|
Packit |
762fc5 |
* Ok, added some minimal floating point support, which means this
|
|
Packit |
762fc5 |
* probably requires libm on most operating systems. Don't yet
|
|
Packit |
762fc5 |
* support the exponent (e,E) and sigfig (g,G). Also, fmtint()
|
|
Packit |
762fc5 |
* was pretty badly broken, it just wasn't being exercised in ways
|
|
Packit |
762fc5 |
* which showed it, so that's been fixed. Also, formated the code
|
|
Packit |
762fc5 |
* to mutt conventions, and removed dead code left over from the
|
|
Packit |
762fc5 |
* original. Also, there is now a builtin-test, just compile with:
|
|
Packit |
762fc5 |
* gcc -DTEST_SNPRINTF -o snprintf snprintf.c -lm
|
|
Packit |
762fc5 |
* and run snprintf for results.
|
|
Packit |
762fc5 |
*
|
|
Packit |
762fc5 |
* Thomas Roessler <roessler@guug.de> 01/27/98 for mutt 0.89i
|
|
Packit |
762fc5 |
* The PGP code was using unsigned hexadecimal formats.
|
|
Packit |
762fc5 |
* Unfortunately, unsigned formats simply didn't work.
|
|
Packit |
762fc5 |
*
|
|
Packit |
762fc5 |
* Michael Elkins <me@cs.hmc.edu> 03/05/98 for mutt 0.90.8
|
|
Packit |
762fc5 |
* The original code assumed that both snprintf() and vsnprintf() were
|
|
Packit |
762fc5 |
* missing. Some systems only have snprintf() but not vsnprintf(), so
|
|
Packit |
762fc5 |
* the code is now broken down under HAVE_SNPRINTF and HAVE_VSNPRINTF.
|
|
Packit |
762fc5 |

|
|
Packit |
762fc5 |
* Andrew Tridgell (tridge@samba.org) Oct 1998
|
|
Packit |
762fc5 |
* fixed handling of %.0f
|
|
Packit |
762fc5 |
* added test for HAVE_LONG_DOUBLE

|
|
Packit |
762fc5 |
* tridge@samba.org, idra@samba.org, April 2001
|
|
Packit |
762fc5 |
* got rid of fcvt code (twas buggy and made testing harder)
|
|
Packit |
762fc5 |
* added C99 semantics

Packit |
762fc5 |
* Thanks to Ollie Oldham <ollie.oldham@metro-optix.com> for spotting it.
|
|
Packit |
762fc5 |
* few mods to make it easier to compile the tests.
|
|
Packit |
762fc5 |
* addedd the "Ollie" test to the floating point ones.

|
|
Packit |
762fc5 |
* Martin Pool (mbp@samba.org) April 2003
|
|
Packit |
762fc5 |
* Remove NO_CONFIG_H so that the test case can be built within a source
|
|
Packit |
762fc5 |
* tree with less trouble.
|
|
Packit |
762fc5 |

* Martin Pool (mbp@samba.org) May 2003
|
|
Packit |
762fc5 |
* Put in a prototype for dummy_snprintf() to quiet compiler warnings.
|
|
Packit |
762fc5 |
*
|
|
Packit |
762fc5 |
* Move #endif to make sure VA_COPY, LDOUBLE, etc are defined even
|
|
Packit |
762fc5 |
* if the C library has some snprintf functions already.
