What do we have in this chapter? In this code, two integers are used to keep track of the number of bytes that are sent and received. The send() and recv() functions both return an integer value of the number of bytes sent or received, respectively, or an error. Each function also takes the same parameters: the active socket, a char buffer, and the number of bytes to send or receive, and any flags to use. Use recvfrom() and sendto() functions for the connectionless socket such as for the User Datagram Protocol (UDP). The following is our complete send, receive and read data for the client and server program examples. Firstly we run the server program to listen for connection. send() and recv() Server Program Example Figure 1 The server program is listening to and waiting for connection.
Send() and recv() Client Program Example Figure 2 And the previous server console output is shown below that complete the server-client communication. Figure 3 Notes for ATM connect() Return Values Remarks Figure 4. Creating a Socket for the Client. Complete Server Code. Complete Client Code.
