Hyperslab selection is an important component of the HDF5 library, and has a wide usage in many applications. While the hyperslab selection API covers many selection operations, it does not allow a user to flexibly operate on two hyperslab selections.The following new APIs were added to provide this capability:

FunctionDescription
H5S_COMBINE_HYPERSLABPerforms an operation on a hyperslab and an existing selection and returns the resulting selection
H5S_COMBINE_SELECT

Combines two hyperslab selections with an operation, returning a dataspace with the resulting selection

H5S_MODIFY_SELECT

Refines a hyperslab selection with an operation using a second hyperslab to modify it

H5S_SEL_ITER_CLOSE

Closes a dataspace selection iterator

H5S_SEL_ITER_CREATECreates a dataspace selection iterator for a dataspace's selection
H5S_SEL_ITER_GET_SEQ_LISTRetrieves a list of offset / length sequences for the elements in an iterator
 H5S_SELECT_ADJUST Adjusts a selection by subtracting an offset
H5S_SELECT_COPYCopies a selection from one dataspace to another
H5S_SELECT_INTERSECT_BLOCKChecks if current selection intersects with a block
H5S_SELECT_PROJECT_INTERSECTIONProjects the intersection of two source selections to a destination selection
H5S_SELECT_SHAPE_SAME
