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 opera‐
tions that is created by calling papiServiceCreate()
job
a pointer to a printer object (initialized to NULL)
to be filled in by papiJobQuery(), papiJobSubmit(),
papiJobSubmitByReference(), papiJobValidate(), papi‐
JobStreamClose(), and papiJobModify()
job_attributes
attributes to apply during job creation or modifica‐
tion
job_id
ID number of the job reported on or manipulated
job_ticket
unused
jobs
a list of job objects returned by papiPrint‐
erListJobs() 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 (papiPrint‐
erListJobs()) 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.
