EFI_STATUS EFIAPI Hash2DriverEntryPoint	(	IN EFI_HANDLE	ImageHandle,
		IN EFI_SYSTEM_TABLE *	SystemTable
	)

The entry point for Hash driver which installs the service binding protocol.

Parameters

[in]	ImageHandle	The image handle of the driver.
[in]	SystemTable	The system table.

Return values

EFI_SUCCESS	The service binding protocols is successfully installed.
Others	Other errors as indicated.

Hash2ServiceBindingCreateChild()

EFI_STATUS EFIAPI Hash2ServiceBindingCreateChild	(	IN EFI_SERVICE_BINDING_PROTOCOL *	This,
		IN OUT EFI_HANDLE *	ChildHandle
	)

Creates a child handle with a set of I/O services.

Parameters

[in]	This	Protocol instance pointer.
[in,out]	ChildHandle	Pointer to the handle of the child to create. If it is NULL, then a new handle is created. If it is not NULL, then the I/O services are added to the existing child handle.

Return values

EFI_SUCCESS	The protocol was added to ChildHandle.
EFI_INVALID_PARAMETER	ChildHandle is NULL.
EFI_OUT_OF_RESOURCES	There are not enough resources available to create the child.
Others	The child handle was not created.

Hash2ServiceBindingDestroyChild()

EFI_STATUS EFIAPI Hash2ServiceBindingDestroyChild	(	IN EFI_SERVICE_BINDING_PROTOCOL *	This,
		IN EFI_HANDLE	ChildHandle
	)

Destroys a child handle with a set of I/O services.

The DestroyChild() function does the opposite of CreateChild(). It removes a protocol that was installed by CreateChild() from ChildHandle. If the removed protocol is the last protocol on ChildHandle, then ChildHandle is destroyed.

Parameters

[in]	This	Pointer to the EFI_SERVICE_BINDING_PROTOCOL instance.
[in]	ChildHandle	Handle of the child to destroy.

Return values

EFI_SUCCESS	The protocol was removed from ChildHandle.
EFI_UNSUPPORTED	ChildHandle does not support the protocol that is being removed.
EFI_INVALID_PARAMETER	ChildHandle is NULL.
EFI_ACCESS_DENIED	The protocol could not be removed from the ChildHandle because its services are being used.
Others	The child handle was not destroyed.
