post_form, unpost_form - write or erase forms from associated subwin- dows
#include <form.h> int post_form(FORM *form); int unpost_form(FORM *form);
The function post_form displays a form to its associated subwindow. To trigger physical display of the subwindow, use refresh(3x) or some equivalent curses routine (the implicit doupdate triggered by an curses input request will do). The function unpost_form erases form from its associated subwindow.
These routines return one of the following: E_OK The routine succeeded. E_BAD_ARGUMENT Routine detected an incorrect or out-of-range argument. E_BAD_STATE Routine was called from an initialization or termination function. E_NOT_POSTED The form has not been posted. E_NOT_CONNECTED No items are connected to the form. E_NO_ROOM Form is too large for its window. E_POSTED The form has already been posted. E_SYSTEM_ERROR System error occurred (see errno(3)).
The header file <form.h> automatically includes the header file <curses.h>.
These routines emulate the System V forms library. They were not sup- ported on Version 7 or BSD versions.
