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