       querysize, int * job_state_mask, char ** callback_url, char ** description)
       Unpack a GRAM Job Request. The globus_gram_protocol_unpack_job_request() function parses
       the job request message packed in the query message and returns copies of the standard
       message attributes in the job_state_mask, callback_url, and description parameters.

       Parameters
           query The unframed job request message to parse.
           querysize The length of the job request message string.
           job_state_mask A pointer to an integer to be set to the job state mask from the job
           request.
           callback_url A pointer to be set with a copy of the URL of the callback contact to be
           registered for this job request. The caller must free this memory by calling free().
           description A pointer to be set to a copy of the job description RSL string for this
           job request. The caller must free this memory by calling free().

       Returns
           Upon success, globus_gram_protocol_unpack_job_request() will return GLOBUS_SUCCESS and
           modify the job_state_mask, callback_url, and description parameters to values
           extracted from the message in query. If an error occurs, an integer error code will be
           returned and the values of job_state_mask, callback_url, and description will be
           undefined.

       Return values
           GLOBUS_SUCCESS Success
           GLOBUS_GRAM_PROTOCOL_ERROR_NULL_PARAMETER Null parameter

   int globus_gram_protocol_unpack_job_request_reply_with_extensions (const globus_byte_t *
       reply, globus_size_t replysize, int * status, char ** job_contact, globus_hashtable_t *
       extensions)
       Unpack a GRAM reply message, parsing all extensions. The
       globus_gram_protocol_unpack_job_request_reply_with_extensions() function parses the reply
       message packed in the reply message parameter and returns copies of the standard message
       attributes in the status and job_contact parameters, and all other extension attributes in
       the hashtable pointed to by extensions. Each entry in the hashtable will be keyed by the
       attribute name and the value will be a pointer to a globus_gram_protocol_extension_t
       structure.

       Parameters
           status A pointer to an integer to be set to the failure code associated with the job
           request. This may be GLOBUS_SUCCESS, if the job request was successful.
           job_contact A pointer to a string to be set to the job contact string. This may set to
           NULL if the job request failed. If
           globus_gram_protocol_unpack_job_request_reply_with_extensions() returns
