IP_RECVORIGDSTADDR(2const) IP_RECVORIGDSTADDR(2const)
IP_RECVORIGDSTADDR - receive IP_ORIGDSTADDR control message
Standard C library (libc, -lc)
#include <netinet/in.h> /* Definition of IP* constants */
#include <sys/socket.h>
int setsockopt(int sockfd, IPPROTO_IP, IP_RECVORIGDSTADDR,
const int *enable, sizeof(int));
This boolean option enables the IP_ORIGDSTADDR ancillary message
in recvmsg(2), in which the kernel returns the original
destination address of the datagram being received.
The ancillary message contains a sockaddr_in(2type) structure.
Not supported for SOCK_STREAM sockets.
See IPPROTO_IP(2const). See setsockopt(2). See ip(7).
Linux.
Linux 2.6.29.
