Split File into Chunks

Demonstrates how to split a file into chunks. Zig

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

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

    const fac = try chilkat.FileAccess.init();
    defer fac.deinit();

    // Any type of file may be split.  It doesn't matter if it's
    // a binary file or a text file.
    const file_to_split = "qa_data/hamlet.xml";

    const part_prefix = "hamlet";
    const part_extension = "part";
    const max_chunk_size = 50000;
    const dest_dir_path = "qa_output";

    // Splits hamlet.xml into hamlet1.part, hamlet2.part, ...
    // Output files are written to the current working directory.
    // Each chunk will be 50000 bytes except for the last which
    // will be the remainder.

    if (fac.splitFile(file_to_split, part_prefix, part_extension, max_chunk_size, dest_dir_path)) {
        std.debug.print("Success.\n", .{});
    } else |_| {
        std.debug.print("{s}\n", .{try fac.getLastErrorText(alloc)});
    }
