41 Retrieves a Unicode string that is the user readable name of the driver.
43 This function retrieves the user readable name of a driver in the form of a
44 Unicode string. If the driver specified by This has a user readable name in
45 the language specified by Language, then a pointer to the driver name is
46 returned in DriverName, and EFI_SUCCESS is returned. If the driver specified
47 by This does not support the language specified by Language,
48 then EFI_UNSUPPORTED is returned.

55 language of the driver name that the caller is
56 requesting, and it must match one of the
57 languages specified in SupportedLanguages. The
58 number of languages supported by a driver is up
59 to the driver writer. Language is specified
60 in RFC 4646 or ISO 639-2 language code format.

97 Retrieves a Unicode string that is the user readable name of the controller
98 that is being managed by a driver.
100 This function retrieves the user readable name of the controller specified by
101 ControllerHandle and ChildHandle in the form of a Unicode string. If the
102 driver specified by This has a user readable name in the language specified by
103 Language, then a pointer to the controller name is returned in ControllerName,
104 and EFI_SUCCESS is returned. If the driver specified by This is not currently
105 managing the controller specified by ControllerHandle and ChildHandle,
106 then EFI_UNSUPPORTED is returned. If the driver specified by This does not
107 support the language specified by Language, then EFI_UNSUPPORTED is returned.
109 @param This[in] A pointer to the EFI_COMPONENT_NAME2_PROTOCOL or
110 EFI_COMPONENT_NAME_PROTOCOL instance.
112 @param ControllerHandle[in] The handle of a controller that the driver
113 specified by This is managing. This handle
114 specifies the controller whose name is to be
117 @param ChildHandle[in] The handle of the child controller to retrieve
118 the name of. This is an optional parameter that
119 may be NULL. It will be NULL for device
120 drivers. It will also be NULL for a bus drivers
121 that wish to retrieve the name of the bus
122 controller. It will not be NULL for a bus
123 driver that wishes to retrieve the name of a
126 @param Language[in] A pointer to a Null-terminated ASCII string
127 array indicating the language. This is the
128 language of the driver name that the caller is
129 requesting, and it must match one of the
130 languages specified in SupportedLanguages. The
131 number of languages supported by a driver is up
132 to the driver writer. Language is specified in
133 RFC 4646 or ISO 639-2 language code format.
135 @param ControllerName[out] A pointer to the Unicode string to return.
136 This Unicode string is the name of the
137 controller specified by ControllerHandle and
138 ChildHandle in the language specified by
139 Language from the point of view of the driver
142 @retval EFI_SUCCESS The Unicode string for the user readable name in
143 the language specified by Language for the
144 driver specified by This was returned in
147 @retval EFI_INVALID_PARAMETER ControllerHandle is NULL.
149 @retval EFI_INVALID_PARAMETER ChildHandle is not NULL and it is not a valid
152 @retval EFI_INVALID_PARAMETER Language is NULL.
154 @retval EFI_INVALID_PARAMETER ControllerName is NULL.
156 @retval EFI_UNSUPPORTED The driver specified by This is not currently
157 managing the controller specified by
158 ControllerHandle and ChildHandle.
