c - getmaxyx 如何改变传递变量的值？

Question

#include <stdio.h>
#include <ncurses.h>

int main() {

  initscr();

  int height, width;
  getmaxyx(stdscr, height, width);

  endwin();

  printf("width  : %i\n", width);
  printf("height : %i\n", height);

  return 0;
}

结果是
宽度:148
高度:38

如何在不传递指针的情况下更改宽度和高度

Notes All of these interfaces are macros. A "&" is not necessary before the variables y and x.
