Hier ist der Client:
| C++: |
#include <windows.h>
#include <iostream>
#define SERVER_IP "127.0.0.1"
#define SERVER_PORT 20000
int main(void)
{
WSADATA wsa;
static struct sockaddr_in sa;
SOCKADDR_IN ca;
fd_set wfds;
struct timeval tv;
// WSAStartup ist obligatorisch
if(WSAStartup(MAKEWORD(2,0),&wsa)!=0)
{
std::cerr << "WSAStartup failure" << std::endl;
WSACleanup();
return 1;
}
SOCKET Client;
Client = socket(AF_INET,SOCK_STREAM,0);
if(Client == INVALID_SOCKET)
{
std::cerr << "Client Socket creation failed" << std::endl;
WSACleanup();
return 1;
}
sa.sin_family=AF_INET;
sa.sin_port=htons(SERVER_PORT);
sa.sin_addr.S_un.S_addr=inet_addr(SERVER_IP);
connect(Client,(SOCKADDR*)&sa,sizeof(sa));
for(;;) // Auf Verbindungen warten
{
// Timeout des Sockets setzen
FD_ZERO(&wfds);
FD_SET(Client, &wfds);
tv.tv_sec = 2; // 2 Sekunden
tv.tv_usec = 0;
int iSelect = select( ((int)Client)+1, NULL, &wfds, NULL, &tv); // (Parameter: Socket, Readable, Writeable, Error, Timeout)
if( SOCKET_ERROR == iSelect )
{
std::cerr << "Fehler: select fehlgeschlagen" << std::endl;
WSACleanup();
return 1;
}
if(FD_ISSET(Client,&wfds)) // Wenn Verbindung da ist
