Function Documentation

   int globus_gram_protocol_pack_job_request (int job_state_mask, const char * callback_url,
       const char * rsl, globus_byte_t ** query, globus_size_t * querysize)
       Pack a GRAM Job Request. The globus_gram_protocol_pack_job_request() function combines its
       parameters into a GRAM job request message body. The caller may frame and send the
       resulting message by calling globus_gram_protocol_post() or just frame it by calling
       globus_gram_protocol_frame_request() and send it by some other mechanism. The
       globus_gram_protocol_pack_job_request() function returns the packed message by modifying
       the query parameter to point to a new string containing the message. The caller is
       responsible for freeing that string.

       Parameters
           job_state_mask The bitwise-or of the GRAM job states which the client would like to
           register for job state change callbacks.
           callback_url A callback contact string which will be contacted when a job state change
           which matches the job_state_mask occurs. This may be NULL, if the client does not wish
           to register a callback contact with this job request. Typically, this value is
           returned in the url parameter to globus_gram_protocol_allow_attach().
           rsl An RSL string which contains the job request. This will be processed on the server
           side.
           query An output parameter which will be set to a new string containing the packed job
           request message. The caller must free this memory by calling free()
           querysize An output parameter which will be populated with the length of the job
           request message returned in query.

       Returns
           Upon success, globus_gram_protocol_pack_job_request() returns GLOBUS_SUCCESS and
           modifies the query and querysize parameters to point to the values described above.

       Return values
           GLOBUS_SUCCESS Success
           GLOBUS_GRAM_PROTOCOL_ERROR_NULL_PARAMETER Null parameter

   int globus_gram_protocol_pack_job_request_reply (int status, const char * job_contact,
       globus_byte_t ** reply, globus_size_t * replysize)
       Pack a GRAM reply message. The globus_gram_protocol_pack_job_request_reply() function
       combines its parameters into a GRAM reply message body. The caller may frame and send the
       resulting message by calling globus_gram_protocol_reply() or just frame it by calling
       globus_gram_protocol_frame_reply() and send it by some other mechanism. The
       globus_gram_protocol_pack_job_request_reply() function returns the packed message by
       modifying the reply parameter to point to a new string containing the message. The caller
       is responsible for freeing that string.

       Parameters
           status The job's failure code if the job failed, or 0, if the job request was
           processed successfully.
           job_contact A string containing the job contact string. This may be NULL, if the job
           request was not successful.
           reply A pointer which will be set to the packed reply string The caller must free this
           string by calling free().
           replysize A pointer which will be set to the length of the reply string.

       Returns
           Upon success, globus_gram_protocol_pack_job_request_reply() returns GLOBUS_SUCCESS and
           modifies the reply and replysize parameters to point to the values described above. If
           an error occurs, an integer error code is returned and the values pointed to by reply
           and replysize are undefined.

       Return values
           GLOBUS_SUCCESS Success

       replysize)
       Pack a GRAM reply message with extension attributes. The
       globus_gram_protocol_pack_job_request_reply_with_extensions() function combines its
       parameters into a GRAM reply message body. The caller may frame and send the resulting
       message by calling globus_gram_protocol_reply() or just frame it by calling

           request was not successful.
           extensions A pointer to a hash table keyed on a string attribute name with the hash
           values being pointers to globus_gram_protocol_extension_t structures. These will be
           encoded in the reply message after the standard attributes.
           reply A pointer which will be set to the packed reply string The caller must free this
           string by calling free().
