/* File : bmove512.c
Author : Michael Widenius;
Defines: bmove512()
bmove512(dst, src, len) moves exactly "len" bytes from the source "src"
to the destination "dst". "src" and "dst" must be alligned on long
boundory and len must be a mutliple of 512 byte. If len is not a
multiple of 512 byte len/512*512+1 bytes is copyed.
bmove512 is moustly used to copy IO_BLOCKS. bmove512 should be the
fastest way to move a mutiple of 512 byte.
