Wait for a Socket to Become Readable

See more Socket/SSL/TLS Examples

Demonstrates Socket.SelectForReading, which waits for read-ready activity on the socket, or on any contained socket when the object is a socket set. It returns 1 if ready, 0 on timeout, or -1 on error.

Background. A timeoutMs of 0 performs a nonblocking poll. With a socket set, this monitors many connections at once for readability.

let socket = chilkat::Socket::new();

// Connect to the server using TLS.
let b_tls = true;
let max_wait_ms = 5000;
if socket.connect("example.com", 5000, b_tls, max_wait_ms).is_err() {
    println!("{}", socket.last_error_text());

// Wait up to 5 seconds for read-ready activity on the socket (or, for a socket set, on any contained
// socket).  Returns 1 if ready, 0 on timeout, or -1 on error.
let ready = socket.select_for_reading(5000);

    println!("{}", socket.last_error_text());
    return;
}

if ready != 1 {
    println!("No data became available before the timeout.");
    return;

println!("The socket has data ready to read.");
