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.

#include "strings.h"

#if VaxAsm

void bfill(dst, len, fill)
char *dst;
int len;
int fill; /* actually char */
{
asm("movc5 $0,*4(ap),12(ap),8(ap),*4(ap)");
}

#else ~VaxAsm

void bfill(dst, len, fill)
register char *dst;
register int len;
register int fill; /* char */
{
while (--len >= 0) *dst++ = fill;

}

#endif VaxAsm

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
