       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.

       Parametersquery 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.
