Typedef Documentation

EFI_SERVICE_BINDING_CREATE_CHILD

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

Creates a child handle and installs a protocol.

The CreateChild() function installs a protocol on ChildHandle. If ChildHandle is a pointer to NULL, then a new handle is created and returned in ChildHandle. If ChildHandle is not a pointer to NULL, then the protocol installs on the existing ChildHandle.

Parameters

This	Pointer to the EFI_SERVICE_BINDING_PROTOCOL instance.
ChildHandle	Pointer to the handle of the child to create. If it is NULL, then a new handle is created. If it is a pointer to an existing UEFI handle, then the protocol is added to the existing UEFI handle.

Return values

EFI_SUCCES	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
other	The child handle was not created

EFI_SERVICE_BINDING_DESTROY_CHILD

typedef EFI_STATUS(EFIAPI * EFI_SERVICE_BINDING_DESTROY_CHILD) (IN EFI_SERVICE_BINDING_PROTOCOL *This, IN EFI_HANDLE ChildHandle)

Destroys a child handle with a protocol installed on it.

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

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

Return values

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