 * Purpose: Prepares JSON parsing error message                               *

 *                                                                            *

 * Parameters: message - [IN] the error message                               *

 *             ptr     - [IN] the failing data fragment                       *

 *             error   - [OUT] the parsing error message (can be NULL)        *

 *                                                                            *

 * Return value: 0 - the json_error() function always returns 0 value         *

 *                      so it can be used to return from failed parses        *

 *                                                                            *
