FTP Download File to a Stream

Demonstrates how to FTP download a file to a Chilkat stream. Zig

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

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

    // This example assumes the Chilkat FTP2 API to have been previously unlocked.
    // See FTP2 Unlock Sample for sample code.

    const ftp = try chilkat.Ftp2.init();
    defer ftp.deinit();

    ftp.setHostname("my-ftp-server.com");
    ftp.setPort(21);
    ftp.setUsername("mFtpLogin");
    ftp.setPassword("myFtpPassword");
    ftp.setAuthTls(true);
    ftp.setPassive(true);

    // Connect and login to the FTP server using TLS.
    ftp.connect() catch {
        std.debug.print("{s}\n", .{try ftp.getLastErrorText(alloc)});
        return;
    };

    // Move to the sub-directory (from the FTP user's home directory) where the file is located.
    ftp.changeRemoteDir("temp") catch {
        std.debug.print("{s}\n", .{try ftp.getLastErrorText(alloc)});
        return;
    };

    // Stream to this local file:
    const stream_obj = try chilkat.Stream.init();
    defer stream_obj.deinit();
    stream_obj.setSinkFile("c:/temp/qa_output/penguins2.jpg");

    ftp.getFileToStream("penguins2.jpg", stream_obj) catch {
