Data Structures
struct	EGgcIt_t
	Structure to store the information relevant to the binary gray code iterator. More...
Defines
#define	EG_GCIT_DBG   0
	Debug level for the heap.
#define	EGgcItClear(__gc)
	free all internally allocated memory for the given EGgcIt_t structure.
#define	EGgcItGetChange(__gc)   ((const int)((__gc)->changed_pos))
	return which position in the binary string changed in the last iteration.
#define	EGgcItGetSize(__gc)   ((const int)((__gc)->sz))
	Return the number of bits for the given gray code iterator.
#define	EGgcItGetTuple(__gc)   ((const int*const)((__gc)->tuple))
	Return a constant pointer to the current tuple.
#define	EGgcItInit(__gc, __sz)
	Initialize a binary gray code iterator, and set the iterator to the zero position.
#define	EGgcItNext(__gc)
	move to the next binary string, if no next string exists (i.e. we finish the loop), return 0, otherwise return 1.
#define	EGgcItReset(__gc)
	Reset an initialized gray code iterator to the zero position.
