void ServerNetworkUDPSocketHandler::Receive_CLIENT_GET_NEWGRFS | ( | Packet * | p, | |
NetworkAddress * | client_addr | |||
) | [protected, virtual] |
A client has requested the names of some NewGRFs.
Replying this can be tricky as we have a limit of SEND_MTU bytes in the reply packet and we can send up to 100 bytes per NewGRF (GRF ID, MD5sum and NETWORK_GRF_NAME_LENGTH bytes for the name). As SEND_MTU is _much_ less than 100 * NETWORK_MAX_GRF_COUNT, it could be that a packet overflows. To stop this we only reply with the first N NewGRFs so that if the first N + 1 NewGRFs would be sent, the packet overflows. in_reply and in_reply_count are used to keep a list of GRFs to send in the reply.
