// but with an additional buffer length check which avoids the buffer overflow errors / security leaks
// quite a number of C/C++ programs suffer from.
//
// Following the C99 standard, a new function snprintf was introduced to take care of this issue.
// However, for god-knows-why Microsoft decided to use a different name, so we are using a define to
// allow for further ingenious cross-platform problems with this...

// NOTE: You still have to include <cstring> to use this function...
