The form windowdisplays any title and border associated with the window; the form subwindowdisplays 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 seteither window; by default, the driver code uses \fBstdscr\fR for both.In the \fBset_\fR functions, window argument of \fBNULL\fR is treated as thoughit were \fBstsdcr\fR.  A form argument of \fBNULL\fR is treated as a requestto change the system default form window or subwindow.The function \fBscale_form\fR returns the minimum size required for thesubwindow of \fIform\fR..SH RETURN VALUERoutines that return pointers return \fBNULL\fR on error.  Routines that returnan integer return one of the following error codes:.TP 5\fBE_OK\fRThe routine succeeded..TP 5\fBE_SYSTEM_ERROR\fRSystem error occurred (see \fBerrno\fR)..TP 5\fBE_BAD_ARGUMENT\fRRoutine detected an incorrect or out-of-range argument..TP 5\fBE_POSTED\fRThe form has already been posted..TP 5\fBE_NOT_CONNECTED\fRNo items are connected to the form..SH SEE ALSO\fBcurses\fR(3X), \fBform\fR(3X)..SH NOTESThe header file \fB<form.h>\fR automatically includes the header file\fB<curses.h>\fR..SH PORTABILITYThese routines emulate the System V forms library.  They were not supported onVersion 7 or BSD versions..SH AUTHORSJuergen Pfeifer.  Manual pages and adaptation for new curses by EricS.
