簽名檔太多不知道該選那一個?!
沒關係..交給亂數決定!!..

適用 sob 原版簽名檔格式 (~/home/dsyan/sig.x , x=1-9) ..
如有動過請自行調整...

edit.c
addsig()
{
  FILE *fs;
  int i;
  char buf[WRAPMARGIN + 1];
  char fpath[STRLEN];
  char ch,tmp=0;
  static char msg[] = "請選擇簽名檔 (1-9, 0=不加, r=亂數)[r]: ";

  srandom(time(0));
  if (!currutmp->userlevel) return;
  i = showsignature(fpath);
  getdata(0, 0, msg, buf, 4, DOECHO, 0);

  if (buf[0]<'0' || buf[0]>'9')
  {
   do {
    buf[0]='1'+random()%9;
    fpath[i] = buf[0];
   } while(!(fs = fopen(fpath, "r"))&&++tmp<20);
   if(tmp<20) fclose(fs);
  }

  if (ch != buf[0] && buf[0] >= '0' && buf[0] <= '9')
  {
    ch = buf[0];
    cuser.uflag = (cuser.uflag & ~SIG_FLAG) | (ch & SIG_FLAG);
  }

  if (ch >= '1' && ch<= '9') {
    fpath[i] = ch;
    if (fs = fopen(fpath, "r"))
    {
      insert_string("\n--\n");
      for (i = 0; i < MAXSIGLINES && fgets(buf, sizeof(buf), fs); i++)
        insert_string(buf);
      fclose(fs);
    }
  }
}

}
