+/*  File   : bmove.c
+    Author : Richard A. O'Keefe.
+	     Michael Widenius;	ifdef MC68000
+    Updated: 23 April 1984
+    Defines: bmove()
+
+    bmove(dst, src, len) moves exactly "len" bytes from the source "src"
+    to the destination "dst".  It does not check for NUL characters as
+    strncpy() and strnmov() do.  Thus if your C compiler doesn't support
+    structure assignment, you can simulate it with
+    bmove(&to, &from, sizeof from);
+    The standard 4.2bsd routine for this purpose is bcopy.  But as bcopy
+    has its first two arguments the other way around you may find this a
+    bit easier to get right.
+    No value is returned.
+
+    Note: the "b" routines are there to exploit certain VAX order codes,
+    but the MOVC3 instruction will only move 65535 characters.	 The asm
+    code is presented for your interest and amusement.
