Zig연습] Cannot use std.io.getStdOut() inside non-main function

 

 

const std = @import("std");

fn output(stream: *std.io.FileOutStream.Stream, s: []const u8) !void {
    return stream.print("Hello world__Zig\n  {}\n", s);
}

pub fn main() !void {
    var stdout_file = try std.io.getStdOut();
    var stdout_stream = std.io.FileOutStream.init(stdout_file);
    var stdout = &stdout_stream.stream;

    try output(stdout, "foo");
}
