Resets the signal on the given handle, ensuring future calls to [[#WaitSynchronization]] on this handle will sleep until the handle is signaled again. If the handle is a ReadableEvent, this is equivalent to calling ClearEvent() on the handle.
Resets the signal on the given handle, ensuring future calls to [[#WaitSynchronization]] on this handle will sleep until the handle is signaled again. If the handle is a ReadableEvent, this returns ResultInvalidState if the event is not signaled.


If the handle is a Process, it will clear the signaled state (which is set when the process changes [[#ProcessState]]. Once the process enters the Exited state, calling ResetSignal on the process will no longer have an effect (the process is permanently signaled), and the syscall will return 0xFA01.

IgnoreExceptionsOfOthers is like IgnoreException but acts on all threads that aren't in the input list. The affected threads are resumed.
ContinueOthers is like ContinueAll but acts on all threads that aren't in the input list. The affected threads are resumed.


Only one of of Resume and IgnoreOtherThreadsExceptions can be set at a time.
Only one of of HandleException and EnableExceptionEvent can be set at a time.


If the input number of threads is 0, this means "all threads".
