C++ Bit Fields

Not too many people knows about C++ Bit Fields. It make decoding binary packet  effortless.

Link to article


struct WeirdPacket
   unsigned int n1 : 1;
   unsigned int n2 : 7;
   unsigned int n3 : 7;
   unsigned int n4 : 17;

To decode:  

WeirdPacket w;   copy(w, buffer, 4); 

Then access your fields ip1.n1 to ip1.n4 at will.


copy also handles endian issue.

buffer points to the begin of weird packet.
