You must call this function if buttons have been changed (e. g. button locked) and these changes are to be displayed on the client (e.g. if locked buttons are to be grayed).
For updating TOP buttons in a TOP button area you have to pass mask Id = 0.
This function cannot be applied to button areas without mask reference (toolboxes). In order to update those, the button area must be completely deleted with the function dal_but_del_but first, and then created and mapped again.
