EFI_REGISTER_RESET_NOTIFY

typedef EFI_STATUS(EFIAPI * EFI_REGISTER_RESET_NOTIFY) (IN EFI_RESET_NOTIFICATION_PROTOCOL *This, IN EFI_RESET_SYSTEM ResetFunction)

Register a notification function to be called when ResetSystem() is called.

The RegisterResetNotify() function registers a notification function that is called when ResetSystem()is called and prior to completing the reset of the platform. The registered functions must not perform a platform reset themselves. These notifications are intended only for the notification of components which may need some special-purpose maintenance prior to the platform resetting. The list of registered reset notification functions are processed if ResetSystem()is called before ExitBootServices(). The list of registered reset notification functions is ignored if ResetSystem()is called after ExitBootServices().

Parameters

[in]	This	A pointer to the EFI_RESET_NOTIFICATION_PROTOCOL instance.
[in]	ResetFunction	Points to the function to be called when a ResetSystem() is executed.

Return values

EFI_SUCCESS	The reset notification function was successfully registered.
EFI_INVALID_PARAMETER	ResetFunction is NULL.
EFI_OUT_OF_RESOURCES	There are not enough resources available to register the reset notification function.
EFI_ALREADY_STARTED	The reset notification function specified by ResetFunction has already been registered.

EFI_UNREGISTER_RESET_NOTIFY

typedef EFI_STATUS(EFIAPI * EFI_UNREGISTER_RESET_NOTIFY) (IN EFI_RESET_NOTIFICATION_PROTOCOL *This, IN EFI_RESET_SYSTEM ResetFunction)

Unregister a notification function.

The UnregisterResetNotify() function removes the previously registered notification using RegisterResetNotify().

Parameters

[in]	This	A pointer to the EFI_RESET_NOTIFICATION_PROTOCOL instance.
[in]	ResetFunction	The pointer to the ResetFunction being unregistered.

Return values

EFI_SUCCESS	The reset notification function was unregistered.
EFI_INVALID_PARAMETER	ResetFunction is NULL.
EFI_INVALID_PARAMETER	The reset notification function specified by ResetFunction was not previously registered using RegisterResetNotify().
