C++ (Cpp) SIN_SET_ADDR Examples

Example #1

File: NetSocket.cpp Project: theAsmodai/rehlds

bool NetSocket::LeaveGroup(NetAddress *group)
{
	ip_mreq mreq;
	SIN_SET_ADDR(&mreq.imr_multiaddr, *(unsigned int *)&group->m_IP[0]);
	SIN_SET_ADDR(&mreq.imr_interface, 0);

	if (setsockopt(m_Socket, IPPROTO_IP, IP_DROP_MEMBERSHIP, (char *)&mreq, sizeof(mreq)) == SOCKET_ERROR)
	{
		int err = m_Network->GetLastErrorCode();
		if (err != WSAEAFNOSUPPORT) {
			m_System->DPrintf("WARNING! NetSocket::LeaveGroup: IP_DROP_MEMBERSHIP: %s\n", m_Network->GetErrorText(err));
		}

		return false;
	}

	return true;
}
