std::string formatting like sprintf

Question

I have to format std::string with sprintf and send it into file stream. How can I do this?

Answer 1

Very-very simple solution.

std::string strBuf;
strBuf.resize(256);
int iCharsPrinted = sprintf_s((char *)strPath.c_str(), strPath.size(), ...);
strBuf.resize(iCharsPrinted);
