PsSetLoadImageNotifyRoutine function

Description

The PsSetLoadImageNotifyRoutine routine registers a driver-supplied callback that is subsequently notified whenever an image (for example, a DLL or EXE) is loaded (or mapped into memory).

Parameters

NotifyRoutine [in]

A pointer to the caller-implemented PLOAD_IMAGE_NOTIFY_ROUTINE callback routine for load-image notifications.

Return value

PsSetLoadImageNotifyRoutine either returns STATUS_SUCCESS or it returns STATUS_INSUFFICIENT_RESOURCES if it failed the callback registration.

Remarks

Highest-level system-profiling drivers can call PsSetLoadImageNotifyRoutine to set up their load-image notify routines (see PLOAD_IMAGE_NOTIFY_ROUTINE).

The maximum number of drivers that can be simultaneously registered to receive load-image notifications is eight. If the maximum number of load-image notify routines is already registered when a driver calls PsSetLoadImageNotifyRoutine to try to register an additional notify routine, PsSetLoadImageNotifyRoutine fails and returns STATUS_INSUFFICIENT_RESOURCES.

Notes

• An update for Windows 8.1 increases the maximum number of drivers registered to receive load-image notifications from eight to 64. This update is installed as part of a cumulative update that is available through Windows Update starting on April 8, 2014. In addition, this cumulative update is available at https://support.microsoft.com/kb/2919355.
• Users of Windows 7 with Service Pack 1 (SP1) can install a hotfix to increase the maximum number of drivers registered to receive load-image notifications from 8 to 64. This hotfix is available at https://support.microsoft.com/kb/2922790.

A driver must remove any callbacks it registers before it unloads. You can remove the callback by calling the PsRemoveLoadImageNotifyRoutine routine.
