Intel® Fortran Compiler 16.0 User and Reference Guide
When a Fortran Console, Fortran QuickWin, or Fortran Standard Graphics application terminates execution, either by normal termination or due to a severe error or exception, the following actions are taken by the Fortran run-time system:
Any Open files are closed and the requested DISPOSITION operations are performed.
With a QuickWin application, any open QuickWin windows are closed.
The C run-time exit() routine is called with the status code to return to the operating system. The C run-time exit() routine will call the Windows API routine ExitProcess to terminate the process. (See crt0dat.c in the C run-time sources).
In a Fortran DLL or Fortran Windows* application, any unhandled I/O programming errors will cause the following actions:
Any Open files are closed and the requested DISPOSITION operations are performed.
The C run-time exit() routine is called with the status code to return to the operating system. The C run-time exit() routine will call the Windows API routine ExitProcess to terminate the process. (See crt0dat.c in the C run-time sources.)
Any unhandled exceptions that occur in a Fortran DLL or Fortran Windows application will have application dependent behavior. Since there is no Fortran default handler present, the behavior depends on what you provide for a handler. If you do not explicitly provide a handler, the default mechanisms provided in your main program will determine the behavior. In a Fortran Windows* application, the C run-time system will terminate the application.
