Name: H5Pmodify_filter
Signature:
herr_t H5Pmodify_filter(hid_t plist, H5Z_filter_t filter_id, unsigned int flags, size_t cd_nelmts, const unsigned int cd_values[] )
Purpose:
Modifies a filter in the filter pipeline.
Description:
H5Pmodify_filter modifies the specified filter_id in the filter pipeline. plist must be a dataset creation property list and the modified filter will be in a permanent filter pipeline.

The filter_id, flags cd_nelmts[], and cd_values parameters are used in the same manner and accept the same values as described in the discussion of H5Pset_filter.

Note:
This function currently supports only the permanent filter pipeline; plist_id must be a dataset creation property list.
Parameters:
Returns:
Returns a non-negative value if successful; otherwise returns a negative value.
