seems difficult....I wrote a program to illustrate the situation of a two dimensions array,more dimensions will be more difficult to implement.
Code:
typedef struct {
	int a;
	int b;
}EMBED;

bool my_sort(EMBED a,EMBED b){
	return a.b > b.b;
}

int main()
{
	int a[10][2];
	EMBED embed_a[10];

	srand(time(NULL));	
	
	for(int i=0;i<10;i++)
		for(int j=0;j<2;j++)
			a[i][j] = rand()%200;
			
	for(int i=0;i<10;i++){		
		embed_a[i].a = a[i][0];
		embed_a[i].b = a[i][1];
	}
	
	vector<EMBED> vec(embed_a,embed_a+10);
	sort(vec.begin(),vec.end(),my_sort);

	for(int i=0;i<10;i++){
		for(int j=0;j<2;j++)
			cout<<a[i][j]<<" ";
		cout<<endl;
	}
	cout<<"============AFTER SORTING==============="<<endl;
	for(vector<EMBED>::const_iterator iter = vec.begin();
								iter != vec.end();iter++)
		cout<<iter->a<<" "<<iter->b<<endl;

	return 0;
}

wresize

wresize(3NCURSES)                                                                                                                wresize(3NCURSES)

NAME

       wresize - resize a curses window

SYNOPSIS

       #include <curses.h>

       int wresize(WINDOW *win, int lines, int columns);

DESCRIPTION

       This is an extension to the curses library.  It reallocates storage for an ncurses window to adjust its dimensions to the specified values.
       If either dimension is larger than the current values, the window's data is filled with blanks that have the current  background  rendition
       (as set by wbkgdset) merged into them.

RETURN VALUE

       The  function returns the integer ERR upon failure and OK on success.  It will fail if either of the dimensions less than or equal to zero,
       or if an error occurs while (re)allocating memory for the window.

NOTES

       The only restriction placed on the dimensions is that they be greater than zero.  The dimensions are not compared to curses  screen  dimen-
       sions to simplify the logic of resizeterm.  The caller must ensure that the window's dimensions fit within the actual screen dimensions.

SEE ALSO

       resizeterm(3NCURSES).
