46 Retrieves a Unicode string that is the user readable name of the driver.

48 This function retrieves the user readable name of a driver in the form of a
49 Unicode string. If the driver specified by This has a user readable name in
50 the language specified by Language, then a pointer to the driver name is
51 returned in DriverName, and EFI_SUCCESS is returned. If the driver specified
52 by This does not support the language specified by Language,
53 then EFI_UNSUPPORTED is returned.

59 language of the driver name that the caller is
60 requesting, and it must match one of the
61 languages specified in SupportedLanguages. The
62 number of languages supported by a driver is up
63 to the driver writer. Language is specified
64 in RFC 3066 or ISO 639-2 language code format.
65 @param [out] ppDriverName A pointer to the Unicode string to return.
66 This Unicode string is the name of the
67 driver specified by This in the language
68 specified by Language.

71 This and the language specified by Language was
72 returned in DriverName.
73 @retval EFI_INVALID_PARAMETER Language is NULL.

118 @param [in] ChildHandle The handle of the child controller to retrieve
119 the name of. This is an optional parameter that
120 may be NULL. It will be NULL for device
121 drivers. It will also be NULL for a bus drivers
122 that wish to retrieve the name of the bus
123 controller. It will not be NULL for a bus
124 driver that wishes to retrieve the name of a
125 child controller.
