The IoRegisterBootDriverCallback routine registers a BOOT_DRIVER_CALLBACK_FUNCTION routine to be called during the initialization of a boot-start driver and its dependent DLLs.
A pointer to the BOOT_DRIVER_CALLBACK_FUNCTION routine to be called when initializing a boot-start driver or DLL.
A driver-defined context to be passed to the BOOT_DRIVER_CALLBACK_FUNCTION routine pointed to by CallbackFunction.
A handle that represents the registration. This handle must be supplied as an input parameter in the call to the IoUnRegisterBootDriverCallback routine that unregisters the BOOT_DRIVER_CALLBACK_FUNCTION routine.
Boot-start drivers must call IoUnRegisterBootDriverCallback and pass the returned handle to unregister the boot-start driver callback before Windows unloads them.
Any error returned from a status update callback is treated as fatal and leads to a system bug check. Additionally, if an initialize image callback returns an error, the driver's image is treated as unknown. To be notified of boot-start driver initialization operations, an early launch anti-malware (ELAM) driver can call IoRegisterBootDriverCallback to register a BOOT_DRIVER_CALLBACK_FUNCTION routine.
