NAME

       post - 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.
