Poll a Socket for Available Data

See more Socket/SSL/TLS Examples

Demonstrates Socket.PollDataAvailable, which performs a nonblocking check for readable activity and returns whether data or another read-ready condition is present.

const std = @import("std");
const chilkat = @import("chilkat");

pub fn main(init: std.process.Init) !void {
    const alloc = init.arena.allocator();

    const socket = try chilkat.Socket.init();
    defer socket.deinit();

    // Connect to the server using TLS.
    const b_tls = true;
    const max_wait_ms = 5000;
    socket.connect("example.com", 5000, b_tls, max_wait_ms) catch {
        std.debug.print("{s}\n", .{try socket.getLastErrorText(alloc)});
        return;
    };

    // Perform a nonblocking check for readable data.  Returns true when data or another read-ready
    // condition is present, and false when nothing is immediately available.
    const b_available = socket.pollDataAvailable();
    if (!b_available) {
        std.debug.print("No data is immediately available.\n", .{});
    } else {
        std.debug.print("Data is available to read.\n", .{});
    }
}
