[Log4cpp-devel] Fixing missing/broken snprintf(): looking for alternatives

[Bastiaan B. <bas...@li...>]

Hi all,

In OstringStream log4cpp uses the vsnprintf() function. Unfortunately 
many platforms either lack this function or have a broken 
implementation. To name a few:

HPUX: broken security hazard, ignores string size parameter.
Solaris:  non C99 compliant return value '-1'.
glibc <= 2.0.6: non C99 compliant return value '-1'.
Tru64: missing (?)

Now log4cpp has an alternative snprintf() implementation in case a C99 
compliant version is not available. Unfortunately it appears not to be 
as portable as we would like. At least on HPUX and Solaris it has been 
reported not to compile.
To resolve the issue I want to replace this implementation with a more 
portable third party one. Both 'Trio"  (http://daniel.haxx.se/trio/ ) 
and "snprintf.c" (http://www.ijs.si/software/snprintf/ ) seem good 
candidates.
If you have experience with either implementation or recommend another 
please let me know!

Thanks,

Bastiaan
