Always returns Errno, normally EINTR.

Examples

let pid = unsafe { nc::fork() };
assert!(pid.is_ok());
let pid = pid.unwrap();
assert!(pid >= 0);

if pid == 0 {
    // child process.
    let mask = nc::sigset_t::default();
    let ret = unsafe { nc::rt_sigsuspend(&mask) };
    assert!(ret.is_ok());
} else {
    // parent process.
    let t = nc::timespec_t {
        tv_sec: 1,
        tv_nsec: 0,
    };
    let ret = unsafe { nc::nanosleep(&t, None) };
    assert!(ret.is_ok());

    let ret = unsafe { nc::kill(pid, nc::SIGTERM) };
    assert!(ret.is_ok());
}
