notcurses_pile(3) notcurses_pile(3) NAME notcurses_pile - operations on Notcurses piles SYNOPSIS struct ncplane* notcurses_top(struct notcurses* n); struct ncplane* notcurses_bottom(struct notcurses* n); struct ncplane* ncpile_top(struct ncplane* n); struct ncplane* ncpile_bottom(struct ncplane* n); DESCRIPTION Notcurses does not export the ncpile type, nor any functionality that uses it directly. Piles are nonetheless an important concept in Notcurses. Functions which operate on piles (e.g. ncpile_render(3) are invoked with any ncplane within that pile. Piles are collections of ncplanes, independent from one another for purposes of rendering and also thread-safety. While only one pile can be rasterized (written to the display) at a time, arbitrary concurrent actions can be safely performed on distinct piles. Piles do not com- pose: rasterizing a pile destroys any overlapping material. A pile is created in one of three ways: • ncpile_create(3) is called, • ncvisual_blit(3) is called with a NULL target plane n, or • ncplane_reparent(3) is called with n equal to newparent, and n is not already a root plane. A pile is destroyed whenever its last ncplane is destroyed, or repar- ented into some other pile. The planes of a pile are totally ordered along the z-axis. ncpile_top and ncpile_bottom return the topmost and bottommost planes, respective- ly, of the pile containing their argument. notcurses_top and notcurs- es_bottom do the same for the standard pile.
