This code is taken from cxmon utility, http://www.uni-mainz.de/~bauec002/,   written by Christian Bauer and Marc Hellwig. Most of their code was   taken from GNU binutils libopcode for i386, which is probably   authored mostly by Pace Willisson. I made several changes, changed   the notation a bit and removed some code, but I'm not the one to take   credit for the functionality of this code (or lack of thereof ;-).*/#include <stdarg.h>#include <stdio.h>#include "nasm/disasm.h"#include "nasm/insns.h" // for pref cpuextern char* describe_address(unsigned int addr);int disass_x86(FILE *f, unsigned int adr) {  char outbuf[256];  long lendis;  char* x;    lendis = disasm((unsigned char*) adr, outbuf, 32, adr, 0 /*FALSE*/, IF_PENT);    fprintf(f,"%08x",adr);  x=describe_address(adr);  if (strlen(x)) fprintf(f," [%s]",x);  fprintf(f, ": \t%s\n", outbuf);    return lendis;}void disass (const char* buf,unsigned int addr,unsigned int len) {  int add=addr;  while (add <= addr+len)    add+=disass_x86(stderr,add);}
