Actually, structured exception handling (SEH) is the closest equivalent of UNIX synchronous signals (SIGSEGV, etc., those that are caused by the program itself) on Win32. As for asynchronous signals, there's APC (asynchronous procedure calls). (See https://msdn.microsoft.com/en-us/library/windows/desktop/ms6...)

I find Win32 vastly superior than UNIX in this area.
