Practical C Programming

How to do it…

1. Define a variable of type sockaddr_in.
2. Invoke the socket function to create a socket. The port number that's specified for the socket is 2000.
3. Call the bind function to assign an IP address to it.
4. Invoke the listen function.
5. Invoke the accept function.
6. Invoke the send function to send the message that was entered by the user to the socket.
7. The socket at the client end will receive the message.

The server program, serverprog.c, for sending a message to the client is as follows:

#include <stdio.h>#include <sys/socket.h>#include <netinet/in.h>#include <string.h>#include <arpa/inet.h>int main(){    int serverSocket, toSend;    char str[255];    struct sockaddr_in server_Address;    serverSocket = socket(AF_INET, SOCK_STREAM, 0); server_Address.sin_family ...
