/* File : strxcat.c
Author : Richard A. O'Keefe.
Updated: 25 may 1984
Defines: strxcat()

strxcat(dst, src1, ..., srcn, NullS)
moves the concatenation of dst,src1,...,srcn to dst, terminates it
with a NUL character, and returns the original value of dst.
It is just like strcat except that it concatenates multiple sources.
Equivalence: strxcat(d, s1, ..., sn) <=> strxcpy(d, d, s1, ..., sn).
Beware: the last argument should be the null character pointer.
Take VERY great care not to omit it! Also be careful to use NullS
and NOT to use 0, as on some machines 0 is not the same size as a
character pointer, or not the same bit pattern as NullS.

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
