This tutorial covers creating sockets, connecting, sending, and receiving data with clear code examples using Vim. Socket Programming in C: TCP Client and Server Socket programming lets your C programs communicate over networks. This tutorial shows how to create a TCP client and server using sockets on Debian 12. TCP Server The server creates a socket, binds to a port, listens for connections, and accepts one client. It then receives a message and replies back. Server Code Example // tcp_server.c #include #include #include #include #include #define PORT 8080 #define BUFFER_SIZE 1024 int main() int server_fd, new_socket; struct sockaddr_in address; int addrlen = sizeof(address); char buffer[BUFFER_SIZE] = 0; char *hello = \\"Hello from server\\"; if ((server_fd = socket(AF_INET, SOCK_STREAM, 0)) == 0) perror(\\"socket failed\\...
