Function glib::source::unix_signal_add_local

pub fn unix_signal_add_local<F>(signum: i32, func: F) -> SourceIdwhere
    F: FnMut() -> Continue + 'static,

Available 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.

Different to unix_signal_add(), this does not require func to be Send but can only be called from the thread that owns the main context.

This function panics if called from a different thread than the one that owns the main context.
