+/*  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 moves up to len
+    characters; dst will be padded on the right with one NUL characters if
+    needed.
