fn wait_for_signal(
pid: Option<Pid>,
wait_signal: Signal,
init_cont: InitialCont,
) -> Result<Pid, ExecEnd>Expand description
Waits for wait_signal. If init_cont, it will first do a ptrace::cont.
We want to avoid that in some cases, like at the beginning of FFI.
If pid is None, only one wait will be done and init_cont should be false.
