Hi,
if i understand you correctly, you need to use one of the following values
as first argument in the H5Sselect_hyperslab function:
>From H5Spublic.h.
/* Different ways of combining selections */
typedef enum H5S_seloper_t {
H5S_SELECT_NOOP = -1, /* error
*/
H5S_SELECT_SET = 0, /* Select "set" operation */
H5S_SELECT_OR, /* Binary "or" operation for hyperslabs
* (add new selection to existing selection)
* Original region: AAAAAAAAAA
* New region: BBBBBBBBBB
* A or B: CCCCCCCCCCCCCCCC
*/
H5S_SELECT_AND, /* Binary "and" operation for hyperslabs
* (only leave overlapped regions in
selection)
* Original region: AAAAAAAAAA
* New region: BBBBBBBBBB
* A and B: CCCC
*/
H5S_SELECT_XOR, /* Binary "xor" operation for hyperslabs
* (only leave non-overlapped regions in
selection)
* Original region: AAAAAAAAAA
* New region: BBBBBBBBBB
* A xor B: CCCCCC CCCCCC
*/
H5S_SELECT_NOTB, /* Binary "not" operation for hyperslabs
* (only leave non-overlapped regions in
original selection)
* Original region: AAAAAAAAAA
* New region: BBBBBBBBBB
* A not B: CCCCCC
*/
H5S_SELECT_NOTA, /* Binary "not" operation for hyperslabs
* (only leave non-overlapped regions in
new selection)
* Original region: AAAAAAAAAA
* New region: BBBBBBBBBB
* B not A: CCCCCC
*/
H5S_SELECT_APPEND, /* Append elements to end of point
selection */
H5S_SELECT_PREPEND, /* Prepend elements to beginning of point
selection */
H5S_SELECT_INVALID /* Invalid upper bound on selection
operations */
} H5S_seloper_t;
