Why would vararg be a problem performance-wise? > More like something along these lines: > > char *tmpdst = dst; > > strcpy (tmpdst, src1); tmpdst += strlen (src1); [...] > This works even better when the strlen calls have known results. Except usually src* are constant strings and it's a major pain from a maintainability and readability point of vue to have to duplicate them. And whenever src* is not a constant, the above is twice as slow as cpycat because each string is read twice (once by strcpy and another time by strlen). -- Francois Gouget [EMAIL PROTECTED] http://fgouget.free.fr/ 1 + e ^ ( i * pi ) = 0
