Re: Purpose of using __be16 inside a data structure?

Hi all,

Please tell me the difference between using unsigned short and __be16 to declear a variable in a data structure. For example, in include/net/inet_sock.h, struct inet_sock is decleared as

struct inet_sock {         __be16                  inet_dport; };

not

struct inet_sock {         unsigned short                  inet_dport; };

This is mostly to avoid confusion about where byte order conversation has to be done. When reading "unsigned short" you would normally expect the variable to contain host byte order. -Michi -- programing a layer 3+4 network protocol for mesh networks see http://michaelblizek.twilightparadox.com
