Function Documentation
int globus_gram_client_register_ping (const char *
resource_manager_contact, globus_gram_client_attr_t attr,
globus_gram_client_nonblocking_func_t register_callback, void *
register_callback_arg)
Send a ping request to a GRAM service. The
globus_gram_client_register_ping() function sends a specially-formatted
GRAM protocol message which checks to see if a Gatekeeper is running on
a given PORT, and whether that Gatekeeper is configured to support the
desired job manager service. This is used for diagnostic purposes.
If globus_gram_client_register_ping() determines that this request
could not be processed before contacting the gatekeeper (for example, a
malformed resource_manager_contact), it will return an error, and the
regiser_callback function will not be called. Otherwise, the success or
failure an be determined by the operation_failure_code parameter to the
function pointed to by the register_callback parameter.
Parameters:
resource_manager_contact A NULL-terminated character string
containing a GRAM contact that this function will contact.
attr A set of client attributes to use to contact the gatekeeper.
If no custom attributes are needed, the caller should pass the
value GLOBUS_GRAM_CLIENT_NO_ATTR.
register_callback A pointer to a function to call when the ping
request has completed or failed.
register_callback_arg A pointer to application-specific data which
will be passed to the function pointed to by register_callback as
its user_callback_arg parameter.
Returns:
Upon success, globus_gram_client_register_ping() returns
GLOBUS_SUCCESS and the register_callback function will be called
once the ping operation completes. If an error occurs, this
function returns an integer error code and the function pointed to
by the register_callback parameter will not be called.
Return values:
GLOBUS_SUCCESS Success
GLOBUS_GRAM_PROTOCOL_ERROR_MALLOC_FAILED Out of memory
GLOBUS_GRAM_PROTOCOL_ERROR_PROTOCOL_FAILED Protocol error
GLOBUS_GRAM_PROTOCOL_ERROR_INVALID_JOB_CONTACT Invalid job contact
GLOBUS_GRAM_PROTOCOL_ERROR_INVALID_REQUEST Invalid request

int globus_gram_client_get_jobmanager_version (const char *
resource_manager_contact, globus_hashtable_t * extensions)
Get version information from a job manager. The
globus_gram_client_get_jobmanager_version() function sends a message to
a GRAM service which returns information about the job manager version
in the value pointed to by the extensions parameter. Note that job
managers prior to GT5 do not support the version request and so will
return a GLOBUS_GRAM_PROTOCOL_ERROR_HTTP_UNPACK_FAILED error. This
function blocks while processing this request.
Parameters:
resource_manager_contact A NULL-terminated character string
containing a GRAM contact.
extensions A pointer to a hash table which will be initialized to
contain the version information returned by the service. The
extensions defined by GRAM5 are toolkit-version and version.
Returns:
Upon success, globus_gram_client_get_jobmanager_version() function
returns GLOBUS_SUCCESS and modifies the extensions parameter as
described above. If an error occurs, the integer error code will be
returned and the value pointed to by the extensions parameter is
undefined.

globus_gram_client_info_callback_func_t info_callback, void *
callback_arg)
Get version information from a job manager without blocking. The
globus_gram_client_register_get_jobmanager_version() function sends a
message to a GRAM service which returns information about the job
manager version to the function pointed to by the info_callback
function. Note that job managers prior to GT5 do not support the
version request and so will return a
GLOBUS_GRAM_PROTOCOL_ERROR_HTTP_UNPACK_FAILED error. This function
blocks while processing this request.
Parameters:
resource_manager_contact A NULL-terminated character string
containing a GRAM contact.
info_callback A pointer to a function to call when the version
request has completed or failed.
callback_arg A pointer to application-specific data which will be
passed to the function pointed to by info_callback as its
user_callback_arg parameter.
Returns:
Upon success, globus_gram_client_register_get_jobmanager_version()
function returns GLOBUS_SUCCESS and begins processing the version
request to contact resource_manager_contact; when complete, the
info_callback function will be called. If an error occurs, the
integer error code will be returned and the value pointed to by the
extensions parameter is undefined.

globus_gram_client_register_job_request() function sends a GRAM
protocol message to a service to request that it start a job on behalf
of the client.
If globus_gram_client_register_job_request() determines that this
request could not be processed before contacting the gatekeeper (for
example, a malformed resource_manager_contact), it will return an
error, and the regiser_callback function will not be called. Otherwise,
the success or failure an be determined by the operation_failure_code
parameter to the function pointed to by the register_callback
parameter.

int globus_gram_client_job_request (const char * resource_manager_contact,
const char * description, int job_state_mask, const char *
callback_contact, char ** job_contact)
Send a job request to a GRAM service. The
globus_gram_client_job_request() function sends a GRAM protocol message
to a service to request that it start a job on behalf of the client.
Unlike, globus_gram_client_register_job_request(),
globus_gram_client_job_request() blocks until the job request has been
processed by the service.
Parameters:
resource_manager_contact A NULL-terminated character string
containing a GRAM contact that this function will contact.
description A pointer to a string containing the job request
information formatted in RSL syntax.
job_state_mask A bitwise-or of the GLOBUS_GRAM_PROTOCOL_JOB_STATE_*
states that the job manager will send job state notification
messages for to the contact named by callback_contact.
callback_contact A GRAM listener contact that the job manager will
send job state notification messages to.
job_contact An output parameter pointing to a string that will be
set to the job contact for this job. This value will only be set if
the job request is successful or the two-phase commit protocol is
being used and the return code is
GLOBUS_GRAM_PROTOCOL_ERROR_WAITING_FOR_COMMIT.
Returns:
Upon success, globus_gram_client_job_request() returns
GLOBUS_SUCCESS and modifies the value pointed to by job_contact as
described above. If an error occurs, this function returns an
integer error code and the value pointed to by job_contact. In
addition to the error codes described below, any
globus_gram_protocol_error_t value may be returned as a cause for
the job to fail.
Return values:
GLOBUS_SUCCESS Success
GLOBUS_GRAM_PROTOCOL_ERROR_MALLOC_FAILED Out of memory
GLOBUS_GRAM_PROTOCOL_ERROR_PROTOCOL_FAILED Protocol error
GLOBUS_GRAM_PROTOCOL_ERROR_INVALID_JOB_CONTACT Invalid job contact

int globus_gram_client_register_job_request_with_info (const char *
resource_manager_contact, const char * description, int job_state_mask,
const char * callback_contact, globus_gram_client_attr_t attr,
globus_gram_client_info_callback_func_t callback, void * callback_arg)
Send a job request to a GRAM service with extensions-aware callback.
The globus_gram_client_register_job_request_with_info() function sends
a GRAM protocol message to a service to request that it start a job on
behalf of the client.
If globus_gram_client_register_job_request_with_info() determines that
this request could not be processed before contacting the gatekeeper
(for example, a malformed resource_manager_contact), it will return an
error, and the callback function will not be called. Otherwise, the
success or failure an be determined by the operation_failure_code
parameter to the function pointed to by the callback parameter. The
difference between this function and
globus_gram_client_register_job_request() is the function signature of
the callback function.
Parameters:
resource_manager_contact A NULL-terminated character string
containing a GRAM contact that this function will contact.
description A pointer to a string containing the job request
information formatted in RSL syntax.
job_state_mask A bitwise-or of the GLOBUS_GRAM_PROTOCOL_JOB_STATE_*
states that the job manager will send job state notification
messages for to the contact named by callback_contact.
callback_contact A GRAM listener contact that the job manager will
send job state notification messages to.
attr A set of client attributes to use to contact the gatekeeper.

messages for to the contact named by callback_contact.
callback_contact A GRAM listener contact that the job manager will
send job state notification messages to.
job_contact An output parameter pointing to a string that will be
set to the job contact for this job. This value will only be set if
the job request is successful or the two-phase commit protocol is
being used and the return code is
GLOBUS_GRAM_PROTOCOL_ERROR_WAITING_FOR_COMMIT.
info An output parameter pointing to a structure to hold the
extensions in the GRAM response. The caller is responsible for
destroying this by calling the
globus_gram_client_job_info_destroy() function.
Returns:
Upon success, globus_gram_client_job_request_with_info() returns
GLOBUS_SUCCESS and modifies the values pointed to by job_contact
and info as described above. If an error occurs, this function
returns an integer error code and the value pointed to by

int globus_gram_client_job_cancel (const char * job_contact)
Cancel a GRAM job. The globus_gram_client_job_cancel() function cancels
a GRAM job. Depending on the job’s current state, this cancellation may
be immediate or require a delay for interacting with the LRM servicing
the job. Notification when the job has been successfully canceled will
be sent to all client contacts registered for notifications after the
cancellation has been completely processed. Unlike,
globus_gram_client_register_job_cancel(),
globus_gram_client_job_cancel() blocks until the job cancel request has
been processed by the service.
Parameters:
job_contact A NULL-terminated character string containing a GRAM
job contact that this function will contact to cancel the job.
Returns:
Upon succes, globus_gram_client_job_cancel() returns GLOBUS_SUCCESS
if the cancellation was successful posted to the service. If an
error occurs, globus_gram_client_job_cancel() returns one of the
globus_gram_protocol_error_t values values indicating why the
client could not cancel the job.

globus_gram_client_register_job_cancel()
int globus_gram_client_register_job_cancel (const char * job_contact,
globus_gram_client_attr_t attr, globus_gram_client_nonblocking_func_t
register_callback, void * register_callback_arg)
Cancel a GRAM job. The globus_gram_client_register_job_cancel()
function sends a message to a GRAM service to cancel a GRAM job.
Depending on the job’s current state, this cancellation may be
immediate or require a delay for interacting with the LRM servicing the
job. In either case, this function returns as soon as it is able to
start sending the message. Notification when the job has been
successfully canceled will be sent to all client contacts registered
for notifications after the cancellation has been completely processed.
Parameters:
job_contact A NULL-terminated character string containing a GRAM
job contact that this function will contact to cancel the job.
attr A set of client attributes to use to contact the job. If no
custom attributes are needed, the caller should pass the value

int globus_gram_client_job_status (const char * job_contact, int *
job_status, int * failure_code)
Send a status query to a GRAM job. The globus_gram_client_status()
function queries the current status of the job associated with the job
contact, returning its current status, as well as the job’s failure
reason if it has failed in this function’s return parameters. This
function blocks until the service has responded to the status query.
Parameters:
job_contact The job contact string of the job to query. This is the
same value returned from globus_gram_client_job_request().
job_status An output parameter that points to an integer to be set
to the current status of the job named by the job_contact
parameter.
failure_code An output parameter that points to an integer to be
set to the reason why the job failed if its current status is
GLOBUS_GRAM_PROTOCOL_JOB_STATE_FAILED. If the job has not failed,
the value will be set to 0.
Returns:
Upon success, the globus_gram_client_job_status() function returns
GLOBUS_SUCCESS, sends a job state query to the job named by
job_contact and parses the service response, modifying the values
pointed to by job_status and failure_code as described above. If an
error occurs, globus_gram_client_job_status() returns an integer
error code.
Return values:

register_callback, void * register_callback_arg)
Send a status query to a GRAM job. The
globus_gram_client_register_job_status() function initiates a query of
the current status of the job associated with the job contact
parameter. The job’s status and failure code are passed to the function
pointed to by the register_callback parameter. This function returns as
soon as it has begun requesting the job status.
Parameters:
job_contact The job contact string of the job to query. This is the
same value returned from globus_gram_client_job_request().
