2 | The EFI_FORM_BROWSER_PROTOCOL is the interface to the EFI\r | |
3 | Configuration Driver. This will allow the caller to direct the\r | |
4 | configuration driver to use either the HII database or use the passed\r | |
5 | in packet of data. This will also allow the caller to post messages\r | |
6 | into the configuration drivers internal mailbox.\r | |

59 | Provides direction to the configuration driver whether to use the HII\r | |
60 | database or a passed-in set of data. This function also establishes a\r | |
61 | pointer to the calling driver's callback interface.\r | |
62 | \r | |
63 | @param This A pointer to the EFI_FORM_BROWSER_PROTOCOL instance.\r | |
64 | @param UseDatabase Determines whether the HII database is to be\r | |
65 | used to gather information. If the value is FALSE, the configuration\r | |
66 | driver will get the information provided in the passed-in Packet parameters.\r | |
67 | @param Handle A pointer to an array of HII handles to display. This value\r | |
68 | should correspond to the value of the HII form package that is required to\r | |
69 | be displayed.\r | |
70 | @param HandleCount The number of handles in the array specified by Handle.\r | |
71 | @param Packet A pointer to a set of data containing pointers to IFR\r | |
72 | and/or string data.\r | |
73 | @param CallbackHandle The handle to the driver's callback interface.\r | |
74 | This parameter is used only when the UseDatabase parameter is FALSE\r | |
75 | and an application wants to register a callback with the browser\r | |
76 | @param NvMapOverride This buffer is used only when there is no NV variable\r | |
77 | to define the current settings and the caller needs to provide to the browser\r | |
78 | the current settings for the "fake" NV variable.\r | |
79 | @param ScreenDimensions Allows the browser to be called so that it occupies\r | |
80 | a portion of the physical screen instead of dynamically determining the\r | |
81 | screen dimensions.\r | |
82 | @param ResetRequired This BOOLEAN value will tell the caller if a reset\r | |
83 | is required based on the data that might have been changed. The ResetRequired\r | |
84 | parameter is primarily applicable for configuration applications, and is an\r | |
85 | optional parameter.\r | |
86 | \r | |
87 | @retval EFI_SUCCESS The function completed successfully\r | |
88 | @retval EFI_NOT_FOUND The variable was not found.\r | |
89 | @retval EFI_BUFFER_TOO_SMALL The DataSize is too small for the result.\r | |
90 | DataSize has been updated with the size needed to complete the request.\r | |
91 | @retval EFI_INVALID_PARAMETER One of the parameters has an invalid value.\r | |
92 | @retval EFI_DEVICE_ERROR The variable could not be saved due to a hardware failure.\r | |
