数据包发送的疑惑
char szPacket[64];
zPacket = szPacket + 2;
zPacket = SetChar( zPacket, S_UDPLOG );
zPacket = SetInteger( zPacket, num );
zPacket = SetInteger( zPacket, saddr.sin_port );
SetShort( szPacket, zPacket - szPacket );
GameWorld.SendRoom( szPacket, zPacket - szPacket, User[num].m_room );
User[num].m_port = saddr.sin_port;
这些发数据包的时候是什么意思啊 不会吧那个覆盖掉吗
