53 Retrieves a Unicode string that is the user readable name of the driver.
55 This function retrieves the user readable name of a driver in the form of a
56 Unicode string. If the driver specified by This has a user readable name in
57 the language specified by Language, then a pointer to the driver name is
58 returned in DriverName, and EFI_SUCCESS is returned. If the driver specified
59 by This does not support the language specified by Language,
60 then EFI_UNSUPPORTED is returned.
62 @param This[in] A pointer to the EFI_COMPONENT_NAME2_PROTOCOL or
63 EFI_COMPONENT_NAME_PROTOCOL instance.
65 @param Language[in] A pointer to a Null-terminated ASCII string
66 array indicating the language. This is the
67 language of the driver name that the caller is
68 requesting, and it must match one of the
69 languages specified in SupportedLanguages. The
70 number of languages supported by a driver is up
71 to the driver writer. Language is specified
72 in RFC 4646 or ISO 639-2 language code format.
74 @param DriverName[out] A pointer to the Unicode string to return.
75 This Unicode string is the name of the
76 driver specified by This in the language
77 specified by Language.
79 @retval EFI_SUCCESS The Unicode string for the Driver specified by
80 This and the language specified by Language was
81 returned in DriverName.
83 @retval EFI_INVALID_PARAMETER Language is NULL.
85 @retval EFI_INVALID_PARAMETER DriverName is NULL.
87 @retval EFI_UNSUPPORTED The driver specified by This does not support
88 the language specified by Language.

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