I am porting a language product from OS/2 to Windows. I have two questions that I need to have answered by some knowledgeable person or persons. 1. Windows Prolog and Epilog. Is this merely for real-mode support? If I know that my application is not going to run in real-mode can I dispense with these? Also, when is the -GW style of prolog-epilog appropriate? 2. Callback functions. The documentation states that all callback functions must be exported. This is confusing to me. Since you pass the instance-address of the function to Windows, why does it need to be exported. Again, is this something that is only necessary for real mode?
