Subject: could anyone help me in the question, thanks?

In network application, we need to fill some fields of protocol header
like below (in C):

struct hdr {
     unsinged short ver;
     unsinged char  len;
     unsinged char  flg;
     ......
};

int main(void)
{
    struct hdr hh;
    hh.ver = 0x1;
    hh.len = 0x2;
    hh.flg = 0x3;
    ...
    send(sock, &hh, sizeof(hh), 0);
    ...
}

How could I do above in Ruby because I don't find how to specify the
data type of variables or the address of variables in Ruby so far? I
will deeply appreciate if anyone gives me any hint about it? Thanks a
lot.
