| Procedure ListDLLExports
|
| Parameters :
| filename : full pathname of DLL to examine
| callback : callback to hand the found exports to, must not be Nil
| Description:
| Loads the passed DLL using the LoadImage function, finds the exported
| names table and reads it. Each found entry is handed to the callback
| for further processing, until no more entries remain or the callback
| returns false. Note that the address passed to the callback for a
exported
| function is an RVA, so not identical to the address the function would
| have in a properly loaded and relocated DLL!
| Error Conditions:
| Exceptions are raised if
| - the passed DLL does not exist or could not be loaded
| - no callback was passed (only if assertions are on)
| - an API function failed
