Microsoft provides a surprisingly good (but proprietary) API inside strsafe.h. StringCchPrintfA can be substituted for snprintf but the return value is different. A small wrapper function around StringCchPrintfExA could get you enough information to emulate snprintf well. But sprintf_s might be good enough for the limited uses inside flac, as you said.

Hi all, There are a bunch of sprintf calls in the FLAC code base and I'd like to replace them with calls to snprintf but I know that can cause problems with at least some versions of Visual Studio. Whats the current state of play in this regard? Erik -- ---------------------------------------------------------------------- Erik de Castro Lopo http://www.mega-nerd.com/
