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

154 driver specified by This was returned in\r
155 DriverName.\r
