Function glib::source::unix_signal_add

pub fn unix_signal_add<F>(signum: i32, func: F) -> SourceId where
    F: FnMut() -> Continue + Send + 'static, 

This is supported on Unix only.

Adds a closure to be called by the default main loop whenever a UNIX signal is raised.

func will be called repeatedly every time signum is raised until it returns Continue(false).

The default main loop almost always is the main loop of the main thread. Thus the closure is called on the main thread. A convenience function for g_unix_signal_source_new(), which attaches to the default MainContext. You can remove the watch using g_source_remove().
