.br
int post_form(FORM *form);
.br
int unpost_form(FORM *form);

.SH DESCRIPTION
The function \fBpost_form\fR displays a form to its associated subwindow.  To
trigger physical display of the subwindow, use \fBrefresh\fR or some equivalent
\fBcurses\fR routine (the implicit \fBdoupdate\fR triggered by an \fBcurses\fR
input request will do).

The function \fBunpost_form\fR erases form from its associated subwindow.
