43 |                    by the form driver to resume form processing. This may
44 |                    be needed after the application calls a curses library
45 |                    I/O routine that modifies the cursor position.
46 |
47 |   Return Values :  E_OK                      - Success
48 |                    E_SYSTEM_ERROR            - System error.
49 |                    E_BAD_ARGUMENT            - Invalid form pointer
50 |                    E_NOT_POSTED              - Form is not posted
