socket 7 processors

In the previous work, I need to develop a simple network data transmission program. Because usually use Delphi to do point development, so this time is no exception. Delphi 7 comes with two sets of TCP socket components: the Indy socket component (Idtcpclient and Idtcpserver) and the Delphi native TCP socket Component

In Windows Phone 7, socket (TCP) communicates with the PC and uses the WP7 simulator to communicate with the simple TCP Service on the PC. The tcp client establishes a socket connection, sends and receives data, and closes the established socket. Using system; using system. net; using system. windows; using system. w

1. In the simplest client/server program, a client is a process and only one connection is initiated, you only need to modify it to allow a client to initiate multiple connections and then use only one connection to send data. First, let's get to know a function getsockname. # Include Int getsockname (INT sockfd, struct sockaddr * ADDR, socklen_t * addrlen ); This function can be used to obtain the address information of a sockfd connection, such as the IP address and port. This helps us determi

Socket programming practices in Linux (7) I/O multiplexing technology-select model Before entering the topic of today's select model, let's take a look at the five I/O models: (1) blocking I/O (this method is used by default) In server socket programming, our common accpet and recv functions are blocked. Taking recv as an example: When the upper-layer applicatio
