From: krish on 12 Jun 2008 02:42 I'm facing some problems while using _vsnprintf in diskperf.c. When I use: length = _vsnprintf (text, sizeof (text) - 1, DebugMessage, ap); I get a warning "warning C4995: '_vsnprintf': name was marked as #pragma deprecated". So used the safer version as: length = _vsnprintf_s (text, sizeof (text), sizeof (text) - 1, DebugMessage, ap); But then I got the errors: diskperf.obj : "error LNK2019: unresolved external symbol __vsnprintf_s referenced in function _DebugPrint" diskperf.sys : "error LNK1120: 1 unresolved externals" It appears that I need to link some other (shared)object. Any help? Thanks.
