184 display a list of the formsets for the handles specified.

186 @param FormSetGuid This field points to the EFI_GUID which must match the Guid
187 field in the EFI_IFR_FORM_SET op-code for the specified
188 forms-based package. If FormSetGuid is NULL, then this
189 function will display the first found forms package.
190 @param FormId This field specifies which EFI_IFR_FORM to render as the first
191 displayable page. If this field has a value of 0x0000, then
192 the forms browser will render the specified forms in their encoded order.
193 @param ScreenDimensions Points to recommended form dimensions, including any non-content area, in
195 @param ActionRequest Points to the action recommended by the form.
197 @retval EFI_SUCCESS The function completed successfully.
198 @retval EFI_INVALID_PARAMETER One of the parameters has an invalid value.
