+/* File : strxnmov.c
+ Author : Richard A. O'Keefe.
+ Updated: 2 June 1984
+ Defines: strxnmov()
+
+ strxnmov(dst, len, src1, ..., srcn, NullS)
+ moves the first len characters of the concatenation of src1,...,srcn
+ to dst. If there aren't that many characters, a NUL character will
+ be added to the end of dst to terminate it properly. This gives the
+ same effect as calling strxcpy(buff, src1, ..., srcn, NullS) with a
+ large enough buffer, and then calling strnmov(dst, buff, len).
+ It is just like strnmov 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.
+
+ Note: strxnmov is like strnmov in that it always moves EXACTLY len
+ characters; dst will be padded on the right with NUL characters as
+ needed. strxncpy does the same. strxncat, like strncat, does NOT.
