Seriously though, how can three different DLLs export functions with the same exact name?

So, yeah, it's a valid design pattern - whether or not the OP actually meant to do that is another matter, of course

char test[] = { 'C', ':', 92, 't', 'e', 's', 't', '.', 'j', 'p', 'g', 0 };

char str[5];
sprintf(str, "%02X%02X", char[0], char[1]);
