Question

我的服务器挂起test=accept(ServSock[i],(LPSOCKADDR)&From,&FromLen);，直到收到连接。如果10秒后没有连接，服务器是否关闭？如何实现呢？

SOCKET test;
    test=accept(ServSock[i],(LPSOCKADDR)&From,&FromLen);
    AmountRead=recv(test, Buffer,sizeof(Buffer),0);
        string xx="abbbbbbfffff55555  rrrrcggggb";
        const char *fin=new char;
        fin=xx.c_str();
        char m;
        fin=xx.c_str();
    RetVal=send(test, fin,xx.length(), 0);
        cout<<"sent: "<<fin<<"\n";
closesocket(test);

fd_set read;
FD_ZERO(&read);
FD_SET(ServSock[i], &read);

struct timeval timeout = { .tv_sec = 10, .tv_usec = 0 };
if (select(ServSock[i] + 1, &read, NULL, NULL, &timeout) == -1)
  return 1;

if (FD_ISSET(ServSock[i], &read)) {
  int ret = accept(ServSock[i],(LPSOCKADDR)&From,&FromLen);
}
else {
  return 1;
}

如何知道我的服务器在一段时间内是否未收到任何连接？
