callback() [1/17]

int callback	(	byte[]	elem,
		long	elem_type,
		int	ndim,
		long[]	point,
		H5D_iterate_t	op_data
	)

application callback for each dataset element

Parameters

elem	the pointer to the element in memory containing the current point
elem_type	the datatype ID for the elements stored in elem
ndim	the number of dimensions for POINT array
