The IoRegisterBootDriverReinitialization routine is called by a boot driver to register the driver's reinitialization routine with the I/O manager to be called after all devices have been enumerated and started.

VOID 
  IoRegisterBootDriverReinitialization(
    IN PDRIVER_OBJECT  DriverObject,
    IN PDRIVER_REINITIALIZE  DriverReinitializationRoutine,
    IN PVOID  Context
    );

Parameters

DriverObject

Pointer to the driver object for the boot driver to be reinitialized.

DriverReinitializationRoutine

Pointer to the driver's Reinitialize routine.

Context

Optional context pointer to be passed to the driver's reinitialization routine.

Return Value

None

Comments

A boot driver normally calls IoRegisterBootDriverReinitialization from its DriverEntry routine, which is run during boot driver initialization. IoRegisterBootDriverReinitialization registers the driver's reinitialization callback routine to be called by the I/O manager after all devices have been enumerated and started. The DriverReinitializationRoutine is run in a system thread at IRQL = PASSIVE_LEVEL.

A driver should call IoRegisterBootDriverReinitialization only if its DriverEntry routine will return STATUS_SUCCESS.

If the DriverReinitializationRoutine uses the registry, the DriverEntry routine must include in IoRegisterBootDriverReinitialization's Context parameter a copy of the string to which DriverEntry's own RegistryPath parameter points.

The DriverEntry routine can call IoRegisterBootDriverReinitialization only once. If the reinitialization routine needs to be run more than once, the DriverReinitializationRoutine can call IoRegisterBootDriverReinitialization as many additional times as needed, using the Count parameter to keep track of the number of times the DriverReinitializationRoutine has been called.

Requirements

IRQL: PASSIVE_LEVEL

Headers: Declared in Ntddk.h and Ntifs.h. Include Ntddk.h or Ntifs.h.
