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

150 the language specified by Language for the\r
151 driver specified by This was returned in\r
152 DriverName.\r

154 @retval EFI_INVALID_PARAMETER ControllerHandle is NULL.\r
