PARAMETERS
attributes a set of attributes to be applied to a printer object
buffer a buffer of data to be written to the job stream
bufflen the size of the supplied buffer
destination the name of the printer where a print job should be relocated, which must reside within the same print services as the
job is currently queued
files files to use during job submission
handle a pointer to a handle to be used for all PAPI operations that is created by calling papiServiceCreate()
job a pointer to a printer object (initialized to NULL) to be filled in by papiJobQuery(), papiJobSubmit(), papiJobSubmit-
ByReference(), papiJobValidate(), papiJobStreamClose(), and papiJobModify()
job_attributes attributes to apply during job creation or modification
job_id ID number of the job reported on or manipulated
job_ticket unused
jobs a list of job objects returned by papiPrinterListJobs() or papiPrinterPurgeJobs()
printer name of the printer where the job is or should reside
requested_attrs a null-terminated array of pointers to attribute names requested during job enumeration (papiPrinterListJobs()) or job
query (papiJobQuery())
stream a communication endpoint for sending print job data
DESCRIPTION
The papiJobSubmit() function creates a print job containing the passed in files with the supplied attributes. When the function returns,
the data in the passed files will have been copied by the print service. A job object is returned that reflects the state of the job.
The papiJobSubmitByReference() function creates a print job containing the passed in files with the supplied attributes. When the function
returns, the data in the passed files might have been copied by the print service. A job object is returned that reflects the state of the
job.
The papiJobStreamOpen(), papiJobStreamWrite(), papiJobStreamClose() functions create a print job by opening a stream, writing to the
stream, and closing it.
The papiJobValidate() function validates that the supplied attributes and files will result in a valid print job.
The papiJobQuery() function retrieves job information from the print service.
The papiJobModify() function modifies a queued job according to the attribute list passed into the call. A job object is returned that
reflects the state of the job after the modification has been applied.
The papiJobMove() function moves a job from its current queue to the named destination within the same print service.
The papiJobCancel() function removes a job from the queue.
The papiJobHold() and papiJobRelease() functions set the job state to "held" or "idle" to indicate whether the job is eligible for process-
ing.
The papiJobRestart() function restarts processing of a currently queued print job.
The papiJobGetAttributeList() function returns a list of attributes describing the job. This list can be searched and/or enumerated using
papiAttributeList*() calls. See papiAttributeListAddValue(3PAPI).
The papiJobGetPrinterName() function returns the name of the queue where the job is currently queued.
The papiJobGetId() function returns a job identifier number from the job object passed in.
The papiJobPromote() function moves a job to the head of the print queue.
The papiJobGetJobTicket() function retrieves a pointer to a job ticket associated with the job object.
The papiJobFree() and papiJobListFree() functions deallocate memory allocated for the return of printer object(s) from functions that
return printer objects.
RETURN VALUES
Upon successful completion, all papiJob*() functions that return a value return PAPI_OK. Otherwise, they return an appropriate papi_sta-
tus_t indicating the type of failure.
Upon successful completion, papiJobGetAttributeList() returns a pointer to the requested data. Otherwise, it returns NULL.
