NAME

notcurses_stdplane - acquire the standard ncplane

SYNOPSIS

#include <notcurses/notcurses.h>

struct ncplane* notcurses_stdplane(struct notcurses* nc);

const struct ncplane* notcurses_stdplane_const(const struct notcurses* nc);

static inline struct ncplane* notcurses_stddim_yx(struct notcurses* nc, int* restrict y, int* restrict x);

DESCRIPTION

notcurses_stdplane returns a handle to the standard ncplane for the context nc. The standard plane always exists, and is always the same size as the screen. It is an error to call ncplane_destroy(3), ncplane_resize(3), or ncplane_move(3) on the standard plane, but it can be freely moved along the z-axis.

notcurses_stddim_yx provides the same function, but also writes the dimensions of the standard plane (and thus the real drawable area) into any non-NULL parameters among y and x.

notcurses_stdplane_const allows a const notcurses to be safely used.

A resize event does not invalidate these references. They can be used until notcurses_stop(3) is called on the associated nc.

RETURN VALUES

These functions cannot fail when provided a valid struct notcurses. They will always return a valid pointer to the standard plane.
