Function glib::source::unix_signal_add_once
source · pub fn unix_signal_add_once<F>(signum: i32, func: F) -> SourceIdwhere
F: FnOnce() + Send + 'static,
Available on Unix only.
Expand description
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.
In comparison to unix_signal_add()
, this only requires func
to be
FnOnce
, and will automatically return Continue(false)
.
