83 specified by Language.\r

115 Routine Description:\r
116 Retrieves a Unicode string that is the user readable name of the controller\r
117 that is being managed by an EFI Driver.\r
118\r
119 Arguments:\r
120 This - A pointer to the EFI_COMPONENT_NAME_PROTOCOL instance.\r
121 ControllerHandle - The handle of a controller that the driver specified by \r
122 This is managing. This handle specifies the controller \r
123 whose name is to be returned.\r
124 ChildHandle - The handle of the child controller to retrieve the name \r
125 of. This is an optional parameter that may be NULL. It \r
126 will be NULL for device drivers. It will also be NULL \r
127 for a bus drivers that wish to retrieve the name of the \r
128 bus controller. It will not be NULL for a bus driver \r
129 that wishes to retrieve the name of a child controller.\r
130 Language - A pointer to a three character ISO 639-2 language \r
131 identifier. This is the language of the controller name \r
132 that that the caller is requesting, and it must match one\r
133 of the languages specified in SupportedLanguages. The \r
134 number of languages supported by a driver is up to the \r
135 driver writer.\r
136 ControllerName - A pointer to the Unicode string to return. This Unicode\r
137 string is the name of the controller specified by \r
138 ControllerHandle and ChildHandle in the language specified\r
139 by Language from the point of view of the driver specified\r
140 by This. \r
141\r
142 Returns:\r
143 EFI_SUCCESS - The Unicode string for the user readable name in the \r
144 language specified by Language for the driver \r
145 specified by This was returned in DriverName.\r
146 EFI_INVALID_PARAMETER - ControllerHandle is not a valid EFI_HANDLE.\r
147 EFI_INVALID_PARAMETER - ChildHandle is not NULL and it is not a valid EFI_HANDLE.\r
148 EFI_INVALID_PARAMETER - Language is NULL.\r
149 EFI_INVALID_PARAMETER - ControllerName is NULL.\r
150 EFI_UNSUPPORTED - The driver specified by This is not currently managing \r
151 the controller specified by ControllerHandle and \r
152 ChildHandle.\r
153 EFI_UNSUPPORTED - The driver specified by This does not support the \r
154 language specified by Language.\r
