| Language, then a pointer to the controller name is returned in ControllerName, | |

| specifies the controller whose name is to be | |
| returned. | |

| the name of. This is an optional parameter that | |
| may be NULL. It will be NULL for device | |
| drivers. It will also be NULL for a bus drivers | |
| that wish to retrieve the name of the bus | |
| controller. It will not be NULL for a bus | |
| driver that wishes to retrieve the name of a | |
| child controller. | |

| controller specified by ControllerHandle and | |
| ChildHandle in the language specified by | |
| Language from the point of view of the driver | |
| specified by This. | |
