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:

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
GLOBUS_GRAM_PROTOCOL_ERROR_HTTP_UNPACK_FAILED Unpack failed
GLOBUS_GRAM_PROTOCOL_ERROR_VERSION_MISMATCH Version mismatch
