Network (Sockets)

Server

You can create a TCP server using socket_server, socket_accept, socket_receive, and socket_send.

// Create server on port 8080
int sockfd = socket_server("127.0.0.1", 8080);

// Accept connection
int client = socket_accept(sockfd);

// Receive data
str msg = socket_receive(client, 1024);
print("Received:", msg);

// Send response
socket_send(client, "Hello Client!");

// Close sockets
socket_close(client);
socket_close(sockfd);

Peer address

socket_peer_ip(fd) returns the remote (client) IP of an accepted connection — handy for logging or rate limiting. It returns "" on error (bad fd, unconnected socket). The Wings/router stack already exposes it on the request as _request["remote_addr"].

int client = socket_accept(sockfd);
str ip = socket_peer_ip(client);   // e.g. "127.0.0.1"
print("connection from", ip);

Client

You can create a TCP client using socket_create, socket_connect, socket_send, and socket_receive.

// Create socket
int sockfd = socket_create();

// Connect to server
socket_connect(sockfd, "127.0.0.1", 8080);

// Send message
socket_send(sockfd, "Hello Server!");

// Receive response
str response = socket_receive(sockfd, 1024);
print("Response:", response);

// Close socket
socket_close(sockfd);
