/**
 * @brief Signals if the job document provided is an AWS IoT Core OTA update document
 *
 * @param jobDoc The job document contained in the AWS IoT Job
 * @param jobDocLength The length of the job document
 * @param fields A pointer to an job document fields structure populated by call
 * @return int8_t The next file index in the job. Returns 0 if no additional files are available. Returns -1 if error.
 *
 * <b>Example</b>
 * @code{c}
 *
 * // The following example shows how to use the otaParser_parseJobDocFile API
 * // to parse out the fields of a received Job Document and populate the fields
 * // of the AfrOtaJobDocumentFields_t stucture.
 *
 * const char * jobDoc;                    // Populated by call to Jobs_GetJobDocument
 * size_t jobDocLength;                    // Return value of Jobs_GetJobDocument
 * int8_t fileIndex = 0;
 * AfrOtaJobDocumentFields_t fields = {0}; // populated by API
 *
 * do
 * {
 *     fileIndex = otaParser_parseJobDocFile(jobDoc,
 *                                           jobDocLength,

 *                                           &fields);
 * } while(fileIndex > 0)
 * // File index will be -1 if an error occurred, and 0 if all files were
 * // processed
 * @endcode
