.SH NAME
panels \- character based panels package
.SH SYNOPSIS
.nf
\fB#include <panel.h>\fR
.fi

.SH DESCRIPTION
The \fBpanel\fR library is built using the \fBcurses\fR library, and any
program using \fBpanels\fR routines must call one of the \fBcurses\fR
initialization routines such as \fBinitscr\fR. A program using these routines
must be compiled with \fB-lpanel\fR and \fB-lcurses\fR on the \fBcc\fR command
line.
.sp
.LP
The \fBpanels\fR package gives the applications programmer a way to have depth
relationships between \fBcurses\fR windows; a \fBcurses\fR window is associated
with every panel. The \fBpanels\fR routines allow \fBcurses\fR windows to
overlap without making visible the overlapped portions of underlying windows.
The initial \fBcurses\fR window, \fBstdscr\fR, lies beneath all panels. The set
of currently visible panels is the \fIdeck\fR of panels.
.sp
.LP
The \fBpanels\fR package allows the applications programmer to create panels,
fetch and set their associated windows, shuffle panels in the deck, and
manipulate panels in other ways.
.SS "Routine Name Index"

.SH RETURN VALUES
Each \fBpanels\fR routine that returns a pointer to an object returns
\fBNULL\fR if an error occurs. Each panel routine that returns an integer,
returns \fBOK\fR if it executes successfully and \fBERR\fR if it does not.
