" approach, not only to establish a connection at the time of the request, but also to be able to reply to the server after the client has made a request to the server.In many cases, the server side is required to proactively push data to the client, keeping the client and server data in real time and in sync.
If a socket connection is established, the server can transmit the data directly to the client
If an HTTP connection is established, the server needs to wait until the client

Original link: http://www.ibm.com/developerworks/cn/linux/l-hisock.htmlUsing the Sockets API, we can develop client and server applications that can communicate on the local network or on a global scale over the Internet. As with other APIs, you can use the Sockets API in a number of ways to improve the performance of the socket or to limit the performance of the socket. This article explores 4 ways to use
interface name, such as eth0 and eth1.Up: Activate the specified network interface card.Down: Disable the specified network interface.Broadcast address: Set the broadcast address of the API.Pointopoint: enables point-to-point.Address: Set the IP address of the specified interface device.Netmask address: Set the subnet mask of the interface.

To resolve this situation, we can lock the interface when there is a network request and not allow the user to do more (the better way is to just lock some buttons rather than the entire interface.) But here's an example of locking the entire interface. Our solution is simple: When Qnetworkaccessmanager makes a request, we enter a new event loop that blocks the operation. Our code example
