Zig Requires Chilkat v11.0.0+

Accept Connection on Socket

See more Socket/SSL/TLS Examples

Demonstrates how to create a TCP/IP socket, listen on a port, accept an incoming connection, and send a "Hello World" message to the client. Zig

const std = @import("std");

    // Bind to a port and listen for incoming connections:
    // This example will listen at port 5555 and allows for a backlog
    // of 25 pending connection requests.
