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 compose: 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 reparented 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, respectively, of the pile containing their argument.  notcurses_top and
       notcurses_bottom do the same for the standard pile.
