The form window +displays any title and border associated with the window; the form subwindow +displays the items of the form that are currently available for selection. + +The first four functions get and set those windows. It is not necessary to set +either window; by default, the driver code uses \fBstdscr\fR for both. + +In the \fBset_\fR functions, window argument of \fBNULL\fR is treated as tbough +it were \fBstsdcr\fR. A form argument of \fBNULL\fR is treated as a request +to change the system default form window or subwindow. + +The function \fBscale_window\fR returns the minimum size required for the +subwindow of \fIform\fR. +.SH RETURN VALUE +Routines that return pointers return \fBNULL\fR on error. Routines that return +an integer return one of the following error codes: +.TP 5 +\fBE_OK\fR +The routine succeeded. +.TP 5 +\fBE_SYSTEM_ERROR\fR +System error occurred (see \fBerrno\fR). +.TP 5 +\fBE_BAD_ARGUMENT\fR +Routine detected an incorrect or out-of-range argument. +.TP 5 +\fBE_POSTED\fR +The form has already been posted. +.TP 5 +\fBE_NOT_CONNECTED\fR +No items are connected to the form. +.SH SEE ALSO +\fBcurses\fR(3X), \fBform\fR(3X). +.SH NOTES +The header file \fB<form.h>\fR automatically includes the header file +\fB<curses.h>\fR. +.SH PORTABILITY +These routines emulate the System V forms library.
