Hi there,

You are lacking one important information: the data length, that is

struct packet {
       enum packet_type type;
	unsigned len;
       void* data;
} packet;

or if you would prefer:

struct packet_header {
       enum packet_type type;
	unsigned len;
}packet_header;


struct packet {
  packet_header hdr;
  void* data;
} packet;




Hope it helps!
