/* 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.
