Else you can use varargs and concatenate all your szFmt into one single string, that you'll feed to f2 this way. I had the same problem once and that's how I did it.

*edit*

code always help

int function1 (const char *fmt, ...)
{
   va_list argptr;
   string temp_string[256];

   // concatenate all the arguments in one string
   va_start (argptr, fmt);
   vsprintf (temp_string, fmt, argptr);
   va_end (argptr);
 
   // call f2
   function2 (temp_string);
}
