  function InquireSignal(RtlSigNum: Integer) : TSignalState;

Description

RtlSigNum will check whether the signal RtlSigNum is being handled, and by whom. It returns a TSignalState result to report the state of the signal, which can be one of the following values:

ssNotHooked
No signal handler is set for the signal.
ssHooked
A signal handler is set by the RTL code for the signal.
ssOverridden
A signal handler was set for the signal by third-party code.

This routine works by resetting the signal handlers, so it is risky to call.
