- /* 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.
