+// a) is returned by main() or winmain(), or
+// b) specified in the call for ExitProcess() or TerminateProcess(), or
+// c) the exception value that causes a process to terminate.
+//
+// It is advisable to not use negative numbers because the Windows API returns
+// it as an unsigned long and the exception values have high numbers. For
+// example EXCEPTION_ACCESS_VIOLATION value is 0xC0000005.
