NAME

6       notcurses_pile - operations on Notcurses piles

SYNOPSIS

9       struct ncplane* notcurses_top(struct notcurses* n);
10
11       struct ncplane* notcurses_bottom(struct notcurses* n);
12
13       struct ncplane* ncpile_top(struct ncplane* n);
14
15       struct ncplane* ncpile_bottom(struct ncplane* n);
16

DESCRIPTION

18       Notcurses  does  not export the ncpile type, nor any functionality that
19       uses it directly.   Piles  are  nonetheless  an  important  concept  in
20       Notcurses.   Functions  which  operate on piles (e.g.  ncpile_render(3)
21       are invoked with any ncplane within that pile.
22
23       Piles are collections of ncplanes, independent  from  one  another  for
24       purposes  of rendering and also thread-safety.  While only one pile can
25       be rasterized (written to the display) at a time, arbitrary  concurrent
26       actions  can  be safely performed on distinct piles.  Piles do not com‐
27       pose: rasterizing a pile destroys any overlapping material.
28
29       A pile is created in one of three ways:
30
31       • ncpile_create(3) is called,
32
33       • ncvisual_blit(3) is called with a NULL target plane n, or
34
35       • ncplane_reparent(3) is called with n equal to newparent, and n is not
36         already a root plane.
37
38       A  pile  is destroyed whenever its last ncplane is destroyed, or repar‐
39       ented into some other pile.
40
41       The planes of a pile are totally ordered along the z-axis.   ncpile_top
42       and ncpile_bottom return the topmost and bottommost planes, respective‐
43       ly, of the pile containing their argument.  notcurses_top and  notcurs‐
44       es_bottom do the same for the standard pile.
