Receive a 16-bit Integer from a Socket

See more Socket/SSL/TLS Examples

Demonstrates Socket.ReceiveInt16, which reads exactly two bytes as a 16-bit integer and stores the result in the ReceivedInt property. Byte order and signedness are selectable.

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;
    };

    // Read exactly two bytes as a 16-bit integer and store the result in the ReceivedInt property.
    // The 1st argument selects byte order (true = big-endian); the 2nd selects unsigned interpretation.
    const b_big_endian = true;
    const b_unsigned = false;
    socket.receiveInt16(b_big_endian, b_unsigned) catch {
        std.debug.print("{s}\n", .{try socket.getLastErrorText(alloc)});
        return;
    };

    std.debug.print("Received 16-bit integer: {d}\n", .{socket.getReceivedInt()});
