post(3form)


NAME

   post_form,   unpost_form   -  write  or  erase  forms  from  associated
   subwindows

SYNOPSIS

   #include <form.h>
   int post_form(FORM *form);
   int unpost_form(FORM *form);

DESCRIPTION

   The function post_form displays a form to its associated subwindow.  To
   trigger  physical  display  of  the  subwindow,  use  refresh  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.

RETURN VALUE

   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).

SEE ALSO

   ncurses(3NCURSES), form(3FORM).

NOTES

   The  header  file  <form.h>  automatically  includes  the  header  file
   <curses.h>.

PORTABILITY

   These routines emulate the System  V  forms  library.   They  were  not
   supported on Version 7 or BSD versions.
