Function rustix::net::sockopt::set_ip_add_membership

pub fn set_ip_add_membership<Fd: AsFd>(
    fd: Fd,
    multiaddr: &Ipv4Addr,
    interface: &Ipv4Addr,
) -> Result<()>

setsockopt(fd, IPPROTO_IP, IP_ADD_MEMBERSHIP, multiaddr, interface)

This is similar to set_ip_add_membership but always sets ifindex value to zero.

See the module-level documentation for more.
