That's not what it does .... you need to either re-read that line or
re-read a book on C programming.

What is type casted is the pointer to gsm48_hdr data field. And that's
because the data field of the gsm48_hdr contains a gsm411_rp_hdr in
this case.

Well, I request you check your claims before making them ...
