◆ globus_gram_protocol_unpack_job_request()

int globus_gram_protocol_unpack_job_request ( const globus_byte_t query,
globus_size_t  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

job_state_maskA pointer to an integer to be set to the job state mask from the job request.
callback_urlA 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().
descriptionA 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.

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.

extensionsA pointer to be set to a hash table containing the names and values of all protocol extensions present in the response message. If globus_gram_protocol_unpack_job_request_reply_with_extensions() returns GLOBUS_SUCCESS, the caller must free this hash table and its values by calling globus_gram_protocol_hash_destroy().

globus_size_t  replysize,
globus_hashtable_t *  extensions 
)

Unpack a GRAM query reply with extensions.

The globus_gram_protocol_unpack_status_reply_with_extensions() function parses the message packed in the reply parameter, storing all attributes and values in a hash table. The extensions parameter is modified to point to that hash table.
