panel_above(3X)

panels deck traversal primitives

From the original Amiga UNIX 2.1 manual. Some things it mentions may not be in this release.

NAME

panel_above: panel_above, panel_below - panels deck traversal primitives

SYNOPSIS

#include <panel.h>

PANEL *panel_above(PANEL *panel);

PANEL *panel_below(PANEL *panel);

DESCRIPTION

panel_above returns a pointer to the panel just above panel, or NULL if panel is the top panel. panel_below returns a pointer to the panel just below panel, or NULL if panel is the bottom panel.

If NULL is passed for panel, panel_above returns a pointer to the bottom panel in the deck, and panel_below returns a pointer to the top panel in the deck.

RETURN VALUE

NULL is returned if an error occurs.

NOTES

These routines allow traversal of the deck of currently visible panels.
