-/* 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.
