    Client server programming hijack

    hey.. can ny1 help me in linking the client n server in c++
    here this is a prog for client test

    Code:
    using namespace jmp_tcp;
    
    
    int main (int argc, char * const argv[]) {
        
        TcpClient client;
    	
    	if(!client.connectByName("localhost", 8000))
    	{
    		std::cout << std::endl << "client connection failed"<< std::endl;
    		return 0;
    	}
    	
    	std::string msg;
    	char buff[256];
    	
    	while(msg != "by")
    	{
    		std::cin >> msg;
    		if(msg.length() >0)
    		{
    			bzero((char *) buff, sizeof(buff));
    			if (!client.send(msg.c_str(), msg.length()))
    			{
    				std::cout<< std::endl << "send error";
    				break;
    			}
    			int len = client.read(buff, sizeof(buff));
    			std::cout << std::endl << len << " " << buff << std::endl;
    
    			if (len <=0) break;
    			else
    			{
    				std::cout << std::endl << len << " " << buff << std::endl;
    			}
    		}
    					
    	}
    	client.disconnect();
    	
    	return 0;
    }
    
    n now i have to send a function
     d->asyncEvent.printOn(std::cout); to the server..
    how can i do dis..
    and dis is the server part
    
    #include <iostream>
    #include "jmp_tcp/TcpServer.h"
    #include "3d_connexion_poc/Protocol.h"
    #include "cfsocket/CFTcpServer.h"
    
    using namespace jmp_tcp;
    
    class ServerTest : public TcpServer 
    {
    
    	protected:
    	
    	virtual void handleConnection(int cfd)
    	{
    		char buff[256];
    		
    		std::cout << "handles a new connection" << std::endl;
    		while(true)
    		{
    			std::cout << " new read " << std::endl;
    
    			bzero((char *) buff, sizeof(buff));
    			int length = recv(cfd, buff, sizeof(buff), 0);
    			std::cout << " length " << length << std::endl;
    
    			if (length <=0) break;
    			else 
    			{
    				send(cfd, buff, length, 0);
    				std::cout << buff << std::endl;
    				if (strcmp(buff, "by")==0) break;
    			}
    			
    		}
    		std::cout << "terminate a connection" << std::endl;
    	}
    };
    
    void dynamicPort()
    {
    	ServerTest server;
    	int port = 8000;
    	while(!server.setup(port) && port <9000)
    	{
    		std::cout << std::endl << "server setup failed for port "<< port <<  std::endl;
    		port++;
    	}
    	
    	std::cout << std::endl << "server running" << std::endl;
    	server.acceptConnections();
    }
    
    void staticPort()
    {
    	ServerTest server;
    	int port = 8000;
    	if(!server.setup(port))
    	{
    		std::cout << std::endl << "server setup failed"<< std::endl;
    		return;
    	}
    	
    	std::cout << std::endl << "server running" << std::endl;
    	server.acceptConnections();
    }
    
    void testProtocol()
    {
    	Protocol<int> p;
    	p.setElementValue("x", 10);
    	p.setElementValue("y", 23);
    	p.setElementValue("z",544);
    	
    	p.printOn(std::cout << std::endl);
    	
    	int length=0;
    	const char* frame = p.getBuffer(length);
    	p.setBuffer(frame, length);
    
    	p.printOn(std::cout << std::endl);
    }
    
    void testCFTcpServer()
    {
    	CFTcpServer server;
    	int port = 8000;
    	if(!server.setup(port))
    	{
    		std::cout << std::endl << "server setup failed"<< std::endl;
    		return;
    	}
    	std::cout << std::endl << "server running"<< std::endl;
    
    	CFRunLoopRun();
    }
    
    int main (int argc, char * const argv[])
    {
    	//staticPort();
    	//dynamicPort();
    	//testProtocol();
    	testCFTcpServer();
    
    	return 0;
    }
