H5P_GET_NFILTERS
Returns the number of filters in the pipeline
Procedure:
H5P_GET_NFILTERS ( plist )
Signature:
int H5Pget_nfilters(hid_t plist)
Fortran90 Interface: h5pget_nfilters_f
SUBROUTINE h5pget_nfilters_f(prp_id, nfilters, hdferr)
IMPLICIT NONE
INTEGER(HID_T), INTENT(IN) :: prp_id ! Dataset creation property
! list identifier
INTEGER, INTENT(OUT) :: nfilters ! The number of filters in
! the pipeline
INTEGER, INTENT(OUT) :: hdferr ! Error code
! 0 on success and -1 on failure
END SUBROUTINE h5pget_nfilters_f
Parameters:
hid_t plist IN: Property list identifier
Description:
H5P_GET_NFILTERS returns the number of filters defined in the filter pipeline associated with the property list plist.
In each pipeline, the filters are numbered from 0 through N-1, where N is the value returned by this function. During output to the file, the filters are applied in increasing order; during input from the file, they are applied in decreasing order.
H5P_GET_NFILTERS returns the number of filters in the pipeline, including zero (0) if there are none.
Returns:
Returns the number of filters in the pipeline if successful; otherwise returns a negative value.
Example:
/* Retrieve filter information. */
plist_id = H5Dget_create_plist (dataset_id);
numfilt = H5Pget_nfilters (plist_id);
CALL h5dget_create_plist_f(dataset_id, plist_id, error)
CALL h5pget_nfilters_f(plist_id, numfilt, error)
