IPPROTO_IP Dans le in.h fichier, le commentaire dit: Dummy protocol for TCP. Cette constante a la valeur 0. C’est en fait un choix automatique selon le type de socket et de la famille. Si vous l’utilisez, et si le type de socket est SOCK_STREAM et de la famille est AF_INET, le protocole sera automatiquement TCP (exactement de la même façon que si vous aviez utilisé IPPROTO_TCP).

The argument for setsockopt(2) is an ip_mreqn or (since Linux 3.5) ip_mreq structure similar to IP_ADD_MEMBERSHIP, or an in_addr structure. (The kernel determines which structure is being passed based on the size passed in optlen .)

If IP_HDRINCL isn’t set, then IP header options can be set on raw sockets with setsockopt(2); see ip(7) for more information. In Linux 2.2, all IP header fields and options can be set using IP socket options.

IP_IPDEFTTL can be used to retrieve the system wide default TTL. If the IP_RECVDSTADDR option is enabled on a SOCK_DGRAM socket, the recvmsg(2) call will return the destination IP address for a UDP datagram. The msg_control field in the msghdr structure points to a buffer that contains a cmsghdr structure followed by the IP address.
