/*-------------------------------------------------------------------------
+ * Function: H5Pmodify_filter
+ *
+ * Purpose: Modifies the specified FILTER in the
+ * transient or permanent output filter pipeline
+ * depending on whether PLIST is a dataset creation or dataset
+ * transfer property list. The FLAGS argument specifies certain
+ * general properties of the filter and is documented below.
+ * The CD_VALUES is an array of CD_NELMTS integers which are
+ * auxiliary data for the filter. The integer vlues will be
+ * stored in the dataset object header as part of the filter
+ * information.
+ *
+ * The FLAGS argument is a bit vector of the following fields:
+ *
+ * H5Z_FLAG_OPTIONAL(0x0001)
+ * If this bit is set then the filter is optional. If the
+ * filter fails during an H5Dwrite() operation then the filter
+ * is just excluded from the pipeline for the chunk for which it
+ * failed; the filter will not participate in the pipeline
+ * during an H5Dread() of the chunk. If this bit is clear and
+ * the filter fails then the entire I/O operation fails.
+ *
+ * Note: This function currently supports only the permanent filter
+ * pipeline. That is, PLIST_ID must be a dataset creation
+ * property list.
+ *
+ * Return: Non-negative on success/Negative on failure
