This function is called by a callback handler to retrieve uncommitted state data from the browser.
This routine is called by a routine which was called by the browser. This routine called this service in the browser to retrieve or set certain uncommitted state information.
This | A pointer to the EFI_FORM_BROWSER2_PROTOCOL instance. | |
ResultsDataSize | A pointer to the size of the buffer associated with ResultsData. On input, the size in bytes of ResultsData. On output, the size of data returned in ResultsData. | |
ResultsData | A string returned from an IFR browser or equivalent. The results string will have no routing information in them. | |
RetrieveData | A BOOLEAN field which allows an agent to retrieve (if RetrieveData = TRUE) data from the uncommitted browser state information or set (if RetrieveData = FALSE) data in the uncommitted browser state information. | |
VariableGuid | An optional field to indicate the target variable GUID name to use. | |
VariableName | An optional field to indicate the target human-readable variable name. |
EFI_SUCCESS | The results have been distributed or are awaiting distribution. | |
EFI_OUT_OF_RESOURCES | The ResultsDataSize specified was too small to contain the results data. |

Initialize the browser to display the specified configuration forms.
This function is the primary interface to the internal forms-based browser. The forms browser will display forms associated with the specified Handles. The browser will select all forms in packages which have the specified Type and (for EFI_HII_PACKAGE_TYPE_GUID) the specified PackageGuid.
This | A pointer to the EFI_FORM_BROWSER2_PROTOCOL instance | |
Handles | A pointer to an array of Handles. This value should correspond to the value of the HII form package that is required to be displayed. | |
HandleCount | The number of Handles specified in Handle. | |
FormSetGuid | This field points to the EFI_GUID which must match the Guid field or one of the elements of the ClassId field in the EFI_IFR_FORM_SET op-code. If FormsetGuid is NULL, then this function will display the form set class EFI_HII_PLATFORM_SETUP_FORMSET_GUID. | |
FormId | This field specifies the identifier of the form within the form set to render as the first displayable page. If this field has a value of 0x0000, then the Forms Browser will render the first enabled form in the form set. | |
ScreenDimensions | Points to recommended form dimensions, including any non-content area, in characters. | |
ActionRequest | Points to the action recommended by the form. |
EFI_SUCCESS | The function completed successfully | |
EFI_NOT_FOUND | The variable was not found. | |
EFI_INVALID_PARAMETER | One of the parameters has an invalid value. |
