PsSetCreateProcessNotifyRoutine function (ntddk.h)

The PsSetCreateProcessNotifyRoutine routine adds a driver-supplied callback routine to, or removes it from, a list of routines to be called whenever a process is created or deleted.


NTSTATUS PsSetCreateProcessNotifyRoutine(
  [in] BOOLEAN                        Remove


[in] NotifyRoutine

Specifies the entry point of a caller-supplied process-creation callback routine. See PCREATE_PROCESS_NOTIFY_ROUTINE.

[in] Remove

Indicates whether the routine specified by NotifyRoutine should be added to or removed from the system's list of notification routines. If FALSE, the specified routine is added to the list. If TRUE, the specified routine is removed from the list.

Return value

PsSetCreateProcessNotifyRoutine can return one of the following:

Return code Description
The given NotifyRoutine is now registered with the system.
The given NotifyRoutine has already been registered, so this call is a redundant call, or the system has reached its limit for registering process-creation callbacks.


Highest-level drivers can call PsSetCreateProcessNotifyRoutine to set up their process-creation notify routines implemented as PCREATE_PROCESS_NOTIFY_ROUTINE.

An IFS or highest-level system-profiling driver might register a process-creation callback to track the system-wide creation and deletion of processes against the driver's internal state. For Windows Vista and later versions of Windows, the system can register up to 64 process-creation callback routines.

A driver must remove any callbacks that it registers before it unloads. You can remove the callback by calling PsSetCreateProcessNotify with Remove = TRUE. A driver must not make this call from its implementation of the PCREATE_PROCESS_NOTIFY_ROUTINE callback routine.

After a driver-supplied routine is registered, it is called with Create set to TRUE just after the initial thread is created within the newly created process designated by the input ProcessId handle. The input ParentId handle identifies the parent process of the newly-created process (this is the parent used for priority, affinity, quota, token, and handle inheritance, among others).
