|
|
.Sh DESCRIPTION
|
|
All output to the screen done by the forms library is handled by the
|
|
curses library routines.
|
|
By default, the forms library will output to the curses
|
|
.Fa stdscr ,
|
|
but if the forms window has been set via
|
|
.Fn set_form_win
|
|
then output will be sent to the window specified by
|
|
.Fn set_form_win ,
|
|
unless the forms subwindow has been set using
|
|
.Fn set_form_sub .
|
|
If a subwindow has been specified using
|
|
.Fn set_form_sub
|
|
then it will be used by the forms library to for screen output.
|
|
The current setting for the form window can be retrieved by calling
|
|
.Fn form_win .
|
|
If the forms window has not been set then
|
|
.Dv NULL
|
|
will be returned.
|
|
Similarly, the forms subwindow can be found by calling the
|
|
.Fn form_sub
|
|
function, again, if the subwindow has not been set then
|
|
.Dv NULL
|
|
will be
|
|
returned.
|
|
The
|
|
.Fn scale_form
|
|
function will return the minimum number of rows and columns that will
|
|
entirely contain the given form.
|
|
.Sh RETURN VALUES
|
|
Functions returning pointers will return
|
|
.Dv NULL
|
|
if an error is detected.
|
|
The functions that return an int will return one of the following error
|
|
values:
|
|
.Pp
|
|
.Bl -tag -width E_UNKNOWN_COMMAND -compact
|
|
.It Er E_OK
|
|
The function was successful.
|
|
.It Er E_NOT_CONNECTED
|
|
The form has no fields connected to it.
|
|
.It Er E_POSTED
|
|
The form is posted to the screen.
