This function gets the data of an invoke associated with a pattern match and returns the length of the data. An invoke means that it was found by a recognizer and a match was created for it. A recognizer is an email address, phone number, PIN, SMS, or URL. If there is no data associated with the invoke, the return value is 0 and p_data points to NULL.
The length of the data in bytes (-1 on error).
