The form library provides terminal-independent facilities for composing form screens on character-cell terminals. The library includes: field routines, which create and modify form fields; and form routines, which group fields into forms, display forms on the screen, and handle interaction with the user.
pos-form-cursor restores the cursor to the position
required for the forms driver to continue processing requests. This is
useful after curses routines have been called to do screen-painting in
response to a form operation.
E_OK if the routine succeeded,
if the routine detected an incorrect or out-of-range argument,
E_NOT_POSTED if the form has not been posted, or
E_SYSTEM_ERROR if a system error occurred.
