An HIU message indicates a handle that was allocated, but never released. An HIU message can indicate that the program has a resource leak.
Purify generates a list of handles in use when you do any one of the following:
§ Exit the program and Handles in use is selected in the Errors and Leaks tab in the Default Settings dialog box or Settings for exename dialog box
§ Call one of the Purify API functions: PurifyAllHandlesInuse or PurifyNewHandlesInuse
§ Specify /HandlesInUseAtExit=yes at the command line
Each message reports the allocation of a single handle. If you see more than one handle allocated, from the same call stack in the program, you should be concerned that you have a handle leak.
