C++ Socket server application control - c++

Question

I am working on a application which works by received commands (API calls) over a socket connection. The application has two socket server with two different port numbers. As said the application is acting on the received commands (string). What is the best way to setup the socket server(s)? The socket server object is been build in a class file and contains two threads (listen for connections, handling the new connected client). The question is, what will be the best way to use the received commands/data so that the application will respond to it. Should I buildin a buffer (vector of string) to store the received data, read this buffer in the main loop of the application and after the reading clear the vector? Or is there a better/ other way?
The code of the socket server class is:
void SocketServer::Startup()
{
WSADATA wsa;
WSAStartup(0x0202, &wsa);
this->WorkerSocket = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
this->EndPnt.sin_addr.s_addr = INADDR_ANY;
this->EndPnt.sin_family = AF_INET;
this->EndPnt.sin_port = htons(this->m_port);
this->Enabled = true;
this->ID = 0;
bind(this->WorkerSocket, (SOCKADDR*)&this->EndPnt, sizeof(this->EndPnt));
printf("[SocketServer]Bound on %d..\n", this->m_port);
listen(this->WorkerSocket, this->Backlog);
CreateThread(0, 0, (LPTHREAD_START_ROUTINE)ServerMainThread, this, NULL, NULL);
}
void SocketServer::WaitForConnections(SocketServer * Ser)
{
while(Ser->Enabled)
{
SOCKET accptsock = accept(Ser->WorkerSocket, NULL, NULL);
printf("[SocketServer]Client connected.\n");
CreateThread(0, 0, (LPTHREAD_START_ROUTINE)ServerDataThread, (LPVOID)accptsock, NULL, NULL);
}
}
void SocketServer::WaitForData(LPVOID lpParam)
{
SOCKET sock = (SOCKET)lpParam;
char *message = "ECHO Daemon v1.0 \r\n";
send(sock, message, strlen(message), 0);
int res;
char buffer[255];
while(true)
{
res = recv(sock, buffer, sizeof(buffer), 0);
if( res == SOCKET_ERROR)
{
int error_code = WSAGetLastError();
if(error_code == WSAECONNRESET)
{
//Somebody disconnected , get his details and print
cout << "[SocketServer]Client disconnected" << endl;
//Close the socket and mark as 0 in list for reuse
closesocket(sock);
ExitThread(0);
}
else
{
closesocket(sock);
ExitThread(0);
}
}
if(res == 0)
{
closesocket(sock);
ExitThread(0);
}
else
{
cout << buffer << endl;
// insert data to vector here
send(sock , buffer , sizeof(buffer) , 0 );
}
}
}
DWORD WINAPI SocketServer::ServerMainThread(LPVOID lParam)
{
((SocketServer*)lParam)->WaitForConnections((SocketServer*)lParam);
return 0;
}
DWORD WINAPI SocketServer::ServerDataThread(LPVOID lParam)
{
((SocketServer*)lParam)->WaitForData((LPVOID)lParam);
return 0;
}
The vector it needs to push the data to is called "Buffer", "Buffer.push_back(buffer)";
