- /* File : strxmov.c
- Author : Richard A. O'Keefe.
- Updated: 25 may 1984
- Defines: strxmov()
- strxmov(dst, src1, ..., srcn, NullS)
- moves the concatenation of src1,...,srcn to dst, terminates it
- with a NUL character, and returns a pointer to the terminating NUL.
- It is just like strmov except that it concatenates multiple sources.
- 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.
