struct ip vs struct iphdr

struct ip vs struct iphdr

[Oleg]

  Hi, all.

It seems struct ip and struct iphdr are similar: struct ip, despite of
it name, doesn't contain anything but ip header.

So, my noob question, what is the difference between them?

Thanks.

BSD vs linux?

struct ip is a BSD-ism, intended to be used if you were porting
some BSD app.

  I saw this. But the answer say that struct ip and struct iphdr defined in
different places. However i see struct iphdr together with struct ip in
my netinet/ip.h. So, i thought that this answer may be inexact or incorrect.

  Thanks!
