C++ (Cpp) string::erase Examples

Example #1

File: MainProcess.cpp Project: CommunicoPublic/iris

//
// Find file in specified list of directories
//
INT_32 MainProcess::FindFile(const STLW::vector<STLW::string>  & vDirectories,
                             const STLW::string                & sFilename,
