967 This is the routine which an external caller uses to direct the browser
968 where to obtain it's information.
971 @param This The Form Browser protocol instanse.
972 @param Handles A pointer to an array of Handles. If HandleCount > 1 we
973 display a list of the formsets for the handles specified.
974 @param HandleCount The number of Handles specified in Handle.
975 @param FormSetGuid This field points to the EFI_GUID which must match the Guid
976 field in the EFI_IFR_FORM_SET op-code for the specified
977 forms-based package. If FormSetGuid is NULL, then this
978 function will display the first found forms package.
979 @param FormId This field specifies which EFI_IFR_FORM to render as the first
980 displayable page. If this field has a value of 0x0000, then
981 the forms browser will render the specified forms in their encoded order.
982 ScreenDimenions - This allows the browser to be called so that it occupies a
983 portion of the physical screen instead of dynamically determining the screen dimensions.
984 ActionRequest - Points to the action recommended by the form.
985 @param ScreenDimensions Points to recommended form dimensions, including any non-content area, in
987 @param ActionRequest Points to the action recommended by the form.
989 @retval EFI_SUCCESS The function completed successfully.
990 @retval EFI_INVALID_PARAMETER One of the parameters has an invalid value.
