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

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