Function Documentation

void globus_gram_protocol_hash_destroy ( globus_hashtable_t * message_hash )

Destroy message attribute hash

Parameters

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

		globus_size_t	replysize,
		int *	status,
		char **	job_contact
	)

Unpack a GRAM reply message.

The globus_gram_protocol_unpack_job_request_reply() function parses the reply message packed in the reply message and returns copies of the standard message attributes in the status and job_contact parameters.

Parameters

reply	The unframed job reply message to parse.
replysize	The length of the reply string.
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() returns GLOBUS_SUCCESS, then the caller must free this string using free().

Returns: Upon success, globus_gram_protocol_unpack_job_request_reply() returns GLOBUS_SUCCESS and modifies the status and job_contact parameters to point to the values described above. If an error occurs, an integer error code is returned and the values pointed to by status and job_contact are 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.

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.

extensions	A 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().
reply	The unframed job reply message to parse.
replysize	The length of the reply string.

Returns: Upon success, globus_gram_protocol_unpack_job_request_reply_with_extensions() returns GLOBUS_SUCCESS and modifies the status, job_contact, and extensions to point to the values described above.

		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. The caller of globus_gram_protocol_unpack_status_reply_with_extensions() must free that hash table by calling globus_gram_protocol_hash_destroy().

replysize	The length of the reply message.
extensions	A pointer to be set to a hash table containing the names and values of all protocol attributes present in the reply message. If globus_gram_protocol_unpack_status_reply_with_extensions() returns GLOBUS_SUCCESS, the caller must free this hash table and its values by calling globus_gram_protocol_hash_destroy().

Returns: Upon success, globus_gram_protocol_unpack_status_reply_with_extensions() returns GLOBUS_SUCCESS and modifies the extensions parameter to point to the value described above. If an error occurs, an integer error code is returned and the value pointed to by extensions is undefined.

		int *	status,
		int *	failure_code
	)

Unpack a GRAM status update message.

The globus_gram_protocol_unpack_status_update_message() function parses the message packed in the reply parameter, storing the standard message attribute values in its return parameters job_contact, status, and failure_code. The caller is responsible for freeing the job_contact value.
