post_form() writes form into its associated subwindow. The application programmer must use curses library routines to display the form on the physical screen or call update_panels() if the panels library is being used.

unpost_form() erases form from its associated subwindow.

These routines return one of the following:

E_OK

The function returned successfully.

E_SYSTEM_ERROR

System error.

E_BAD_ARGUMENT

An argument is incorrect.

E_POSTED

The form is posted.

E_NOT_POSTED

The form is not posted.

E_NO_ROOM

The form does not fit in the subwindow.

E_BAD_STATE

The routine was called from an initialization or termination function.

E_NOT_CONNECTED

The field is not connected to a form.
