45 Retrieves a Unicode string that is the user readable name of the driver.
47 This function retrieves the user readable name of a driver in the form of a
48 Unicode string. If the driver specified by This has a user readable name in
49 the language specified by Language, then a pointer to the driver name is
50 returned in DriverName, and EFI_SUCCESS is returned. If the driver specified
51 by This does not support the language specified by Language,
52 then EFI_UNSUPPORTED is returned.
54 @param This[in] A pointer to the EFI_COMPONENT_NAME2_PROTOCOL or
55 EFI_COMPONENT_NAME_PROTOCOL instance.
57 @param Language[in] A pointer to a Null-terminated ASCII string
58 array indicating the language. This is the
59 language of the driver name that the caller is
60 requesting, and it must match one of the
61 languages specified in SupportedLanguages. The
62 number of languages supported by a driver is up
63 to the driver writer. Language is specified
64 in RFC 3066 or ISO 639-2 language code format.
66 @param DriverName[out] A pointer to the Unicode string to return.
67 This Unicode string is the name of the
68 driver specified by This in the language
69 specified by Language.
71 @retval EFI_SUCCESS The Unicode string for the Driver specified by
72 This and the language specified by Language was
73 returned in DriverName.
75 @retval EFI_INVALID_PARAMETER Language is NULL.
77 @retval EFI_INVALID_PARAMETER DriverName is NULL.

101 Retrieves a Unicode string that is the user readable name of the controller
102 that is being managed by a driver.
104 This function retrieves the user readable name of the controller specified by
105 ControllerHandle and ChildHandle in the form of a Unicode string. If the
106 driver specified by This has a user readable name in the language specified by
107 Language, then a pointer to the controller name is returned in ControllerName,
108 and EFI_SUCCESS is returned. If the driver specified by This is not currently
109 managing the controller specified by ControllerHandle and ChildHandle,
110 then EFI_UNSUPPORTED is returned. If the driver specified by This does not
111 support the language specified by Language, then EFI_UNSUPPORTED is returned.
113 @param This[in] A pointer to the EFI_COMPONENT_NAME2_PROTOCOL or
114 EFI_COMPONENT_NAME_PROTOCOL instance.
116 @param ControllerHandle[in] The handle of a controller that the driver
117 specified by This is managing. This handle
118 specifies the controller whose name is to be
121 @param ChildHandle[in] The handle of the child controller to retrieve
122 the name of. This is an optional parameter that
123 may be NULL. It will be NULL for device
124 drivers. It will also be NULL for a bus drivers
125 that wish to retrieve the name of the bus
126 controller. It will not be NULL for a bus
127 driver that wishes to retrieve the name of a
130 @param Language[in] A pointer to a Null-terminated ASCII string
131 array indicating the language. This is the
132 language of the driver name that the caller is
133 requesting, and it must match one of the
134 languages specified in SupportedLanguages. The
135 number of languages supported by a driver is up
136 to the driver writer. Language is specified in

139 @param ControllerName[out] A pointer to the Unicode string to return.
140 This Unicode string is the name of the
141 controller specified by ControllerHandle and
142 ChildHandle in the language specified by
143 Language from the point of view of the driver
146 @retval EFI_SUCCESS The Unicode string for the user readable name in
147 the language specified by Language for the
148 driver specified by This was returned in

153 @retval EFI_INVALID_PARAMETER ChildHandle is not NULL and it is not a valid
156 @retval EFI_INVALID_PARAMETER Language is NULL.
