Hare by Example: Exit

Use os::exit() to immediately terminate the process and exit with the given status. Any deferred functions will also get called before the process exits.

use fmt;
use os;

export fn main() void = {
	defer fmt::println("narp")!;

	os::exit(3);
};

$ hare run exit.ha
narp

$ hare build exit.ha 
4/4 tasks completed (100%)

$ ./exit
narp

$ echo $?
3
