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);**
static inline const struct ncplane notcurses_stddim_yx_const(const 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.
The standard plane's virtual cursor is initialized to its uppermost, leftmost cell unless NCOPTION_PRESERVE_CURSOR is provided (see notcurses_init(3)), in which case it is placed wherever the terminal's real cursor was at startup.
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.
