Awhile ago a program called x2macbin was posted. In it is a function call bzero that is not defined anywhere. Can anyone supply me with 1) a working version of this program, 2) a lsiting of the needed function, 3) or describe what it is supposed to do, so I can write my own. Thanks much, Mike Robins hounx!mlr (201) 949-4150

I wrote and posted macbin, an xbin to macbinary program which may somewhere have gotten renamed. It used bcopy a BSD library function. The following is from stringlib, a public domain reimplementation of the string libraries by Author : Richard A. O'Keefe. The entire library was posted, I believe in mod.sources. Here is bcopy.c from it. ------------------------< not a shar, just edit>--------------------- /* File : bcopy.c Author : Richard A. O'Keefe. Updated: 23 April 1984 Defines: bcopy() bcopy(src, dst, 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 bcopy(&from, &to, sizeof from); BEWARE: the first two arguments are the other way around from almost everything else. I'm sorry about that, but that's the way it is in the 4.2bsd manual, though they list it as a bug. For a version with the arguments the right way around, use bmove(). 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. */ #include "strings.h" #if VaxAsm void bcopy(src, dst, len) char *src, *dst; int len; { asm("movc3 12(ap),*4(ap),*8(ap)"); } #else ~VaxAsm void bcopy(src, dst, len) register char *src, *dst; register int len; { while (--len >= 0) *dst++ = *src++; } #endif VaxAsm -- Jim Budler Advanced Micro Devices, Inc.
