Subject apr_snprintf not compliant
Date Thu, 22 Aug 2002 19:07:41 GMT

apr_snprintf and apr_vsnprintf are not compliant with the POSIX snprint
standard currently.  There are two problems.  1)  a length of 0 should
allow the buffer to be NULL, and it should return the computed length of
the requested string.  This doesn't currently happen.  2)  Specifying a
string precision doesn't work correctly.  The common reason for specifying
a string precision, is that you don't ahve a NULL-terminated string, but
we always call strlen on the string that is passed in.  Problem 2 is in
GNATS as bug 8554, and it has a fix.  Problem 1 is not in any bug DB, but
I have a fix already.

My question, is whether we really want to fix these problems, because we
don't _have_ to be POSIX compliant.  My own opinion is that they should be
