pub fn unix_signal_add<F>(signum: i32, func: F) -> SourceId
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 ControlFlow::Break
.
The default main loop almost always is the main loop of the main thread. Thus, the closure is called on the main thread.
