H5P_SET_FILTER_CALLBACK sets the user-defined filter callback function func in the dataset transfer property list plist. The parameter op_data is a pointer to user-defined input data for the callback function and will be passed through to the callback function. The callback function func defines the actions an application is to take when a filter fails. The function prototype is as follows: typedef H5Z_cb_return_t (H5Z_filter_func_t) (H5Z_filter_t filter_id, void *buf, size_t buf_size, void *op_data)where filter_id indicates which filter has failed, buf and buf_size are used to pass in the failed data, and op_data is the required input data for this callback function. Valid callback function return values are H5Z_CB_FAIL and H5Z_CB_CONT. |
