◆ Dhcp4DriverBindingStart()

EFI_STATUS EFIAPI Dhcp4DriverBindingStart	(	IN EFI_DRIVER_BINDING_PROTOCOL *	This,
		IN EFI_HANDLE	ControllerHandle,
		IN EFI_DEVICE_PATH_PROTOCOL *RemainingDevicePath	OPTIONAL
	)

Start this driver on ControllerHandle. This service is called by the EFI boot service ConnectController(). In order to make drivers as small as possible, there are a few calling restrictions for this service. ConnectController() must follow these calling restrictions. If any other agent wishes to call Start() it must also follow these calling restrictions.

Parameters

[in]	This	Protocol instance pointer.
[in]	ControllerHandle	Handle of device to bind driver to
[in]	RemainingDevicePath	Optional parameter use to pick a specific child device to start.

Return values

EFI_SUCCESS	This driver is added to ControllerHandle
EFI_ALREADY_STARTED	This driver is already running on ControllerHandle
other	This driver does not support this device

Definition at line 282 of file Dhcp4Driver.c.

◆ Dhcp4DriverBindingStop()

EFI_STATUS EFIAPI Dhcp4DriverBindingStop	(	IN EFI_DRIVER_BINDING_PROTOCOL *	This,
		IN EFI_HANDLE	ControllerHandle,
		IN UINTN	NumberOfChildren,
		IN EFI_HANDLE *	ChildHandleBuffer
	)

Stop this driver on ControllerHandle. This service is called by the EFI boot service DisconnectController(). In order to make drivers as small as possible, there are a few calling restrictions for this service. DisconnectController() must follow these calling restrictions. If any other agent wishes to call Stop() it must also follow these calling restrictions.

Parameters

[in]	This	Protocol instance pointer.
[in]	ControllerHandle	Handle of device to stop driver on
[in]	NumberOfChildren	Number of Handles in ChildHandleBuffer. If number of children is zero stop the entire bus driver.
[in]	ChildHandleBuffer	List of Child Handles to Stop.

Return values

EFI_SUCCESS	This driver is removed ControllerHandle
other	This driver was not removed from this device

Definition at line 402 of file Dhcp4Driver.c.

◆ Dhcp4DriverBindingSupported()

EFI_STATUS EFIAPI Dhcp4DriverBindingSupported	(	IN EFI_DRIVER_BINDING_PROTOCOL *	This,
		IN EFI_HANDLE	ControllerHandle,
		IN EFI_DEVICE_PATH_PROTOCOL *RemainingDevicePath	OPTIONAL
	)

Test to see if this driver supports ControllerHandle. This service is called by the EFI boot service ConnectController(). In order to make drivers as small as possible, there are a few calling restrictions for this service. ConnectController() must follow these calling restrictions. If any other agent wishes to call Supported() it must also follow these calling restrictions.

Parameters

[in]	This	Protocol instance pointer.
[in]	ControllerHandle	Handle of device to test
[in]	RemainingDevicePath	Optional parameter use to pick a specific child device to start.

Return values

EFI_SUCCESS	This driver supports this device
EFI_ALREADY_STARTED	This driver is already running on this device
other	This driver does not support this device

◆ Dhcp4ServiceBindingCreateChild()

EFI_STATUS EFIAPI Dhcp4ServiceBindingCreateChild	(	IN EFI_SERVICE_BINDING_PROTOCOL *	This,
		IN 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_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
other	The child handle was not created

Definition at line 535 of file Dhcp4Driver.c.

◆ Dhcp4ServiceBindingDestroyChild()

EFI_STATUS EFIAPI Dhcp4ServiceBindingDestroyChild	(	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_SUCCESS	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
