[Help] how to know size of a string with an arguments?

[Anti]

void Log::outChar(const char * str, ... )
{

   if (!str)
       return;

   if(charLogfile)
   {
       va_list ap;
       outTimestamp(charLogfile);
       va_start(ap, str);
       vfprintf(charLogfile, str, ap);
       fprintf(charLogfile, "\\n" );
       va_end(ap);
       fflush(charLogfile);
   }
}

I need to know size of completed str (with args) which send into log file.

I think you can use strlen on the char pointer.

The answer was close

vfprint and the same fucntions return value of written chars.
