Function glib::source::unix_fd_add_local

pub fn unix_fd_add_local<F>(
    fd: RawFd, 
    condition: IOCondition, 
    func: F
) -> SourceId where
    F: FnMut(RawFd, IOCondition) -> Continue + 'static, 

This is supported on Unix only.

Adds a closure to be called by the main loop the returned Source is attached to whenever a UNIX file descriptor reaches the given IO condition.

func will be called repeatedly while the file descriptor matches the given IO condition 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_fd_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.
