Hi,
From ip(4) :
SYNOPSIS
#include <sys/socket.h>
#include <netinet/in.h>
However this fails :
$ cat > ip.c
#include <sys/socket.h>
#include <netinet/in.h>
int main() {
return 0;
}
^D
$ gcc ip.c

Including <sys/types.h> before <sys/socket.h> makes it ok.
So either the manual is wrong
or sys/socket.h or netinet/in.h is wrong.
