H5P_GET_HYPER_VECTOR_SIZE
Retrieves number of I/O vectors to be read/written in hyperslab I/O
Procedure:
H5P_GET_HYPER_VECTOR_SIZE ( dxpl_id, vector_size )
Signature:
herr_t H5Pget_hyper_vector_size(hid_t dxpl_id,
size_t *vector_size
)
Fortran90 Interface: h5pget_hyper_vector_size_f
SUBROUTINE h5pget_hyper_vector_size_f(plist_id, size, hdferr)
IMPLICIT NONE
INTEGER(HID_T), INTENT(IN) :: plist_id ! Dataset transfer property list
! identifier
INTEGER(SIZE_T), INTENT(OUT) :: size ! Vector size
INTEGER, INTENT(OUT) :: hdferr ! Error code
! 0 on success and -1 on failure
END SUBROUTINE h5pget_hyper_vector_size_f
Parameters:
hid_t dxpl_id | IN: Dataset transfer property list identifier |
size_t *vector_size | OUT: Number of I/O vectors to accumulate in memory for I/O operations |
Description:
H5P_GET_HYPER_VECTOR_SIZE retrieves the number of I/O vectors to be accumulated in memory before being issued to the lower levels of the HDF5 library for reading or writing the actual data.
The number of I/O vectors set in the dataset transfer property list dxpl_id is returned in vector_size. Unless the default value is in use, vector_size was previously set with a call to H5P_SET_HYPER_VECTOR_SIZE.
Returns:
Returns a non-negative value if successful; otherwise returns a negative value.
