Retrieves the offset of a field of a compound datatype
Procedure:
H5T_GET_MEMBER_OFFSET (dtype_id, memb_no)
Signature:
size_t H5Tget_member_offset( hid_t dtype_id, unsigned memb_no )
SUBROUTINE h5tget_member_offset_f(type_id, member_no, offset, hdferr)
IMPLICIT NONE
INTEGER(HID_T), INTENT(IN) :: type_id ! Datatype identifier
INTEGER, INTENT(IN) :: member_no ! Number of the field
! whose offset is requested
INTEGER(SIZE_T), INTENT(OUT) :: offset ! Byte offset of the the
! beginning of the field
INTEGER, INTENT(OUT) :: hdferr ! Error code
END SUBROUTINE h5tget_member_offset_f
Parameters:
hid_t dtype_id | IN: Identifier of datatype to query |
unsigned memb_no | IN: Number of the field whose offset is requested |
Description:
H5T_GET_MEMBER_OFFSET retrieves the byte offset of the beginning of a field within a compound datatype with respect to the beginning of the compound datatype datum.
Returns:
Returns the byte offset of the field if successful; otherwise returns 0 (zero). Note that zero is a valid offset and that this function will fail only if a call to H5Tget_member_class() fails with the same arguments.
Example:
History:
| Release | Change |
|---|
| 1.6.4 | membno parameter type changed to unsigned. |
