/* File : bfill.c
Author : Richard A. O'Keefe.
Michael Widenius; ifdef MC68000
Updated: 23 April 1984
Defines: bfill()
bfill(dst, len, fill) moves "len" fill characters to "dst".
Thus to set a buffer to 80 spaces, do bfill(buff, 80, ' ').
Note: the "b" routines are there to exploit certain VAX order codes,
but the MOVC5 instruction will only move 65535 characters. The asm
code is presented for your interest and amusement.
