Re: [reSIProcate] Visual Studio 2005 compilation warnings of 1.4 branch


Jason,

yeah, you're right, this mainly affects ares....

Very true, but I really doubt that it's possible to achieve the
Behavior of the *_s functions (ie. not to copy anything to the 
dest buffer if it's not large enough) without iterating through 
the string two times....

I read about these strl* functions but I thought that those are 
OpenBSD specific. If there are free implementations for all relevant 
functions (not just for strlcpy) then I'd really be fine with 
using this approach! (not just because it would avoid MSVC compiler
warnings ;-)
