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;
}

mouse_setposition_6d

mouse_getposition_6d(3) 					Svgalib User Manual					   mouse_getposition_6d(3)

NAME

       mouse_getposition_6d, mouse_setposition_6d, mouse_setrange_6d - provide an interface to 3d mice

SYNOPSIS

       #include <vgamouse.h>

       void mouse_getposition_6d(int *x, int *y, int *z, int *rx , int *ry, int *rz);
       void mouse_setposition_6d(int x, int y, int z, int rx , int ry, int rz, int dim_mask);
       void  mouse_setrange_6d(int  x1,  int  x2,  int	y1,  int  y2,  int z1 , int z2, int rx1, int rx2, int ry1, int ry2 , int rz1, int rz2, int
       dim_mask);

DESCRIPTION

       These routines provide the same function as mouse_getx(3), mouse_gety(3), mouse_setxrange(3), mouse_setyrange(3), mouse_setposition(3), and
       mouse_getx(3), except that they work in all six dimensions, x, y, z, and rotations about those axes.

       For mouse_getposition_6d(), NULL pointers may be passed for any coordinate you don't care to know about.  Those dimensions will be ignored.

       mouse_setposition_6d() and mouse_setrange_6d() take an additional argument called dim_mask, which should be an logical or of the following:
       MOUSE_XDIM, MOUSE_YDIM, MOUSE_ZDIM, MOUSE_RXDIM, MOUSE_RYDIM, or MOUSE_RZDIM.  MOUSE_2DIM, MOUSE_3DIM, MOUSE_6DIM can be used as  shorthand
       for the XY, XYZ, or XYZRxRyRz dimensions.  The position or ranges will only be set if that dimension is included in dim_mask.

       The 6d mouse routines can be used safely with any mouse type, including standard 2D mice.

       When used with mice that support fewer than six axes, the other coordinates will always return zero (or whatever value you set them to).
