setsockopt: SO_RCVTIMEO

Hi,

I am trying to set receive timeout on my raw socket but it keeps telling me "invalid argument". Is there something I'm missing here?

Code:

int val = 0;
if (setsockopt(s, SOL_SOCKET, SO_RCVTIMEO, &val, sizeof(val))) {
       perror("setsockopt: rcvtimeo");
       exit(1);
}

Nevermind. It seems it takes a timeval as argument.

Code:

        int val = 0;  
        struct timeval tv;
        tv.tv_sec = 30;  /* 30 Secs Timeout */
if (setsockopt(s, SOL_SOCKET, SO_RCVTIMEO, (struct timeval *)&tv,sizeof(struct timeval)) {
       perror("setsockopt: rcvtimeo");
       exit(1);
}
