The
BaseSocketManager
class is about 99 percent of what you need to create a
client-side socket manager or a server-side socket manager. Classes that inherit
from it can make it easy to create connections between clients and servers.
An easy example of an extension of the
BaseSocketManager
class is a class to
manage the client side of a game. Its job is to create a single socket that attaches to
a known server.
class ClientSocketManager : public BaseSocketManager
{
std::string m_HostName;
unsigned int m_Port;
public:
ClientSocketManager(const std::string &hostName, unsigned int port)
