20 Retrieves a Unicode string that is the user-readable name of the driver.
22 This function retrieves the user-readable name of a driver in the form of a
23 Unicode string. If the driver specified by This has a user-readable name in
24 the language specified by Language, then a pointer to the driver name is
25 returned in DriverName, and EFI_SUCCESS is returned. If the driver specified
26 by This does not support the language specified by Language,
27 then EFI_UNSUPPORTED is returned.
29 @param[in] This A pointer to the EFI_COMPONENT_NAME2_PROTOCOL or
30 EFI_COMPONENT_NAME_PROTOCOL instance.
32 @param[in] Language A pointer to a Null-terminated ASCII string
33 array indicating the language. This is the
34 language of the driver name that the caller is
35 requesting, and it must match one of the
36 languages specified in SupportedLanguages. The
37 number of languages supported by a driver is up
38 to the driver writer. Language is specified
39 in RFC 4646 or ISO 639-2 language code format.
41 @param[out] DriverName A pointer to the Unicode string to return.
42 This Unicode string is the name of the
43 driver specified by This in the language
44 specified by Language.
46 @retval EFI_SUCCESS The Unicode string for the Driver specified by
47 This and the language specified by Language was
48 returned in DriverName.
50 @retval EFI_INVALID_PARAMETER Language is NULL.
52 @retval EFI_INVALID_PARAMETER DriverName is NULL.
54 @retval EFI_UNSUPPORTED The driver specified by This does not support
55 the language specified by Language.

75 and EFI_SUCCESS is returned. If the driver specified by This is not currently
76 managing the controller specified by ControllerHandle and ChildHandle,
77 then EFI_UNSUPPORTED is returned. If the driver specified by This does not
78 support the language specified by Language, then EFI_UNSUPPORTED is returned.

81 EFI_COMPONENT_NAME_PROTOCOL instance.
83 @param[in] ControllerHandle The handle of a controller that the driver
84 specified by This is managing. This handle
85 specifies the controller whose name is to be
88 @param[in] ChildHandle The handle of the child controller to retrieve
89 the name of. This is an optional parameter that
90 may be NULL. It will be NULL for device
91 drivers. It will also be NULL for a bus drivers
92 that attempt to retrieve the name of the bus
93 controller. It will not be NULL for a bus
94 driver that attempts to retrieve the name of a
97 @param[in] Language A pointer to a Null-terminated ASCII string
98 array indicating the language. This is the
99 language of the driver name that the caller is
100 requesting, and it must match one of the

102 number of languages supported by a driver is up
103 to the driver writer. Language is specified in
104 RFC 4646 or ISO 639-2 language code format.
106 @param[out] ControllerName A pointer to the Unicode string to return.
107 This Unicode string is the name of the
108 controller specified by ControllerHandle and
109 ChildHandle in the language specified by
110 Language, from the point of view of the driver
113 @retval EFI_SUCCESS The Unicode string for the user-readable name in
114 the language specified by Language for the
115 driver specified by This was returned in
118 @retval EFI_INVALID_PARAMETER ControllerHandle is NULL.
120 @retval EFI_INVALID_PARAMETER ChildHandle is not NULL, and it is not a valid
123 @retval EFI_INVALID_PARAMETER Language is NULL.
125 @retval EFI_INVALID_PARAMETER ControllerName is NULL.
127 @retval EFI_UNSUPPORTED The driver specified by This is not currently
128 managing the controller specified by
129 ControllerHandle and ChildHandle.
