Error: cannot return non-void from void function

[Suliman via Digitalmars-d-learn]

Full function look like this:

auto parseConfig()
{
	auto config = Ini.Parse(getcwd ~ "\\" ~ "config.ini");
	string txtlinks = getcwd ~ "\\" ~ config.getKey("input_links");
	if(!exists(txtlinks))
	{
		writeln("Can't find input file with list of links.");
		return;
	}
	auto lines = File(txtlinks, "r").byLine;
	return lines;

}
