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

unpost_form(FORM *form);
DESCRIPTION
The post_form() function performs the actions necessary to present the form on the curses screen. If there are any init functions that need to be called then they will be called prior to the form being posted and the cursor will be positioned on the first active field that can be visited. Conversely, the function unpost_form() removes the form from the screen and calls any termination functions that were specified.
