Looks alright.

and in my_element.cc file if I have

p->data() returns a const pointer, so you would have to use:
     const char *x = (const char *)p->data();

Alternatively if you need write access use the following:
     WritablePacket *wp = p->uniqueify();
     char *x = wp->data();

Also if I want to send 128 bit through click to a program outside click

You could, but much simpler is to just use the Socket Element to send data.
You can even use the existing Socket element in your element above i.e.

sock::Socket(TCP, 127.0.0.1,1322)->[0]my_element;
my_element -> Queue -> sock;

The input port of socket is agnostic, so you could push directly into
Socket, but if pushed, packets will block on the underlying socket. If pull
input is used the socket will pull packets as it can accept them.
