Another option if you are on linux is to use eventfd. Then you
can trigger it with simple write on eventfd descriptor.
As far as waiting goes it’s either read on descriptor or
poll/select.
f it seems a bit more involved.

However I’d be super careful about mutexes with signal

signal safe.
There's also signalfd which is quite practical to change signals
in select/poll/epoll events.
