◆ Udp6DriverBindingSupported()

EFI_STATUS EFIAPI Udp6DriverBindingSupported	(	IN EFI_DRIVER_BINDING_PROTOCOL *	This,
		IN EFI_HANDLE	ControllerHandle,
		IN EFI_DEVICE_PATH_PROTOCOL *RemainingDevicePath	OPTIONAL
	)

Tests to see if this driver supports a given controller. If a child device is provided, it further tests to see if this driver supports creating a handle for the specified child device.

This function checks to see if the driver specified by This supports the device specified by ControllerHandle. Drivers typically use the device path attached to ControllerHandle and/or the services from the bus I/O abstraction attached to ControllerHandle to determine if the driver supports ControllerHandle. This function may be called many times during platform initialization. In order to reduce boot times, the tests performed by this function must be very small, and take as little time as possible to execute. This function must not change the state of any hardware devices, and this function must be aware that the device specified by ControllerHandle may already be managed by the same driver or a different driver. This function must match its calls to AllocatePages() with FreePages(), AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol(). Since ControllerHandle may have been previously started by the same driver, if a protocol is already in the opened state, then it must not be closed with CloseProtocol(). This is required to guarantee the state of ControllerHandle is not modified by this function.

Parameters

[in]	This	A pointer to the EFI_DRIVER_BINDING_PROTOCOL instance.
[in]	ControllerHandle	The handle of the controller to test. This handle must support a protocol interface that supplies an I/O abstraction to the driver.
[in]	RemainingDevicePath	A pointer to the remaining portion of a device path. This parameter is ignored by device drivers, and is optional for bus drivers. For bus drivers, if this parameter is not NULL, then the bus driver must determine if the bus controller specified by ControllerHandle and the child controller specified by RemainingDevicePath are both supported by this bus driver.

Return values

EFI_SUCCESS	The device specified by ControllerHandle and RemainingDevicePath is supported by the driver specified by This.
EFI_ALREADY_STARTED	The device specified by ControllerHandle and RemainingDevicePath is already being managed by the driver specified by This.
EFI_ACCESS_DENIED	The device specified by ControllerHandle and RemainingDevicePath is already being managed by a different driver or an application that requires exclusive access. Currently not implemented.
EFI_UNSUPPORTED	The device specified by ControllerHandle and RemainingDevicePath is not supported by the driver specified by This.

Tests to see if this driver supports a given controller. If a child device is provided, it further tests to see if this driver supports creating a handle for the specified child device.

This function checks to see if the driver specified by This supports the device specified by ControllerHandle. Drivers will typically use the device path attached to ControllerHandle and/or the services from the bus I/O abstraction attached to ControllerHandle to determine if the driver supports ControllerHandle. This function may be called many times during platform initialization. In order to reduce boot times, the tests performed by this function must be very small, and take as little time as possible to execute. This function must not change the state of any hardware devices, and this function must be aware that the device specified by ControllerHandle may already be managed by the same driver or a different driver. This function must match its calls to AllocatePages() with FreePages(), AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol(). Because ControllerHandle may have been previously started by the same driver, if a protocol is already in the opened state, then it must not be closed with CloseProtocol(). This is required to guarantee the state of ControllerHandle is not modified by this function.

Parameters

[in]	This	A pointer to the EFI_DRIVER_BINDING_PROTOCOL instance.
[in]	ControllerHandle	The handle of the controller to test. This handle must support a protocol interface that supplies an I/O abstraction to the driver.
[in]	RemainingDevicePath	A pointer to the remaining portion of a device path. This parameter is ignored by device drivers, and is optional for bus drivers. For bus drivers, if this parameter is not NULL, then the bus driver must determine if the bus controller specified by ControllerHandle and the child controller specified by RemainingDevicePath are both supported by this bus driver.

Return values

EFI_SUCCESS	The device specified by ControllerHandle and RemainingDevicePath is supported by the driver specified by This.
EFI_ALREADY_STARTED	The device specified by ControllerHandle and RemainingDevicePath is already being managed by the driver specified by This.
EFI_ACCESS_DENIED	The device specified by ControllerHandle and RemainingDevicePath is already being managed by a different driver or an application that requires exclusive access. Currently not implemented.
EFI_UNSUPPORTED	The device specified by ControllerHandle and RemainingDevicePath is not supported by the driver specified by This.

◆ Udp6ServiceBindingCreateChild()

EFI_STATUS EFIAPI Udp6ServiceBindingCreateChild	(	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

[in]	This	Pointer to the EFI_SERVICE_BINDING_PROTOCOL instance.
[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 a pointer to an existing UEFI handle, then the protocol is added to the existing UEFI handle.

Return values

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

◆ Udp6ServiceBindingDestroyChild()

EFI_STATUS EFIAPI Udp6ServiceBindingDestroyChild	(	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	Protocol instance pointer.
[in]	ChildHandle	Handle of the child to destroy.

Return values

EFI_SUCCESS	The I/O services were removed from the child handle.
EFI_UNSUPPORTED	The child handle does not support the I/O services that are being removed.
EFI_INVALID_PARAMETER	Child handle is NULL.
EFI_ACCESS_DENIED	The child handle could not be destroyed because its I/O services are being used.
other	The child handle was not destroyed.
