DESCRIPTION

The function deregisters event notification callbacks forthe caller identified by ModuleGuid. The CSSM_ModuleUnload() function is the analog call to CSSM_ModuleLoad().

Calls to CSSM_ModuleUnload() that are not matched with a previous call to CSSM_ModuleLoad() result in an error.

The CSSM uses the three input parameters ModuleGuid, AppNotifyCallback, and AppNotifyCallbackCtx touniquely identify registered callbacks.

This function should be invoked after all necessary callsto CSSM_ModuleDetach() have been performed.
