.SH DESCRIPTION
.sp
.LP
The \fBpapiJobSubmit()\fR 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.
.sp
.LP
The \fBpapiJobSubmitByReference()\fR 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.
.sp
.LP
The \fBpapiJobStreamOpen()\fR, \fBpapiJobStreamWrite()\fR,
\fBpapiJobStreamClose()\fR functions create a print job by opening a stream,
writing to the stream, and closing it.
.sp
.LP
The \fBpapiJobValidate()\fR function validates that the supplied attributes and
files will result in a valid print job.
.sp
.LP
The \fBpapiJobQuery()\fR function retrieves job information from the print
service.
.sp
.LP
The \fBpapiJobModify()\fR 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.
.sp
.LP
The \fBpapiJobMove()\fR function moves a job from its current queue to the
named destination within the same print service.
.sp
.LP
The \fBpapiJobCancel()\fR function removes a job from the queue.
.sp
.LP
The \fBpapiJobHold()\fR and \fBpapiJobRelease()\fR functions set the job state
to "held" or "idle" to indicate whether the job is eligible for processing.
.sp
.LP
The \fBpapiJobRestart()\fR function restarts processing of a currently queued
print job.
.sp
.LP
The \fBpapiJobGetAttributeList()\fR function returns a list of attributes
describing the job. This list can be searched and/or enumerated using
\fBpapiAttributeList*()\fR calls. See \fBpapiAttributeListAddValue\fR(3PAPI).
.sp
.LP
The \fBpapiJobGetPrinterName()\fR function returns the name of the queue where
the job is currently queued.
.sp
.LP
The \fBpapiJobGetId()\fR function returns a job identifier number from the job
object passed in.
.sp
.LP
The \fBpapiJobPromote()\fR function moves a job to the head of the print queue.
.sp
.LP
The \fBpapiJobGetJobTicket()\fR function retrieves a pointer to a job ticket
associated with the job object.
.sp
.LP
The \fBpapiJobFree()\fR and \fBpapiJobListFree()\fR functions deallocate memory
allocated for the return of printer object(s) from functions that return
printer objects.
.SH RETURN VALUES
.sp
.LP
Upon successful completion, all \fBpapiJob*()\fR functions that return a value
return \fBPAPI_OK\fR. Otherwise, they return an appropriate \fBpapi_status_t\fR
indicating the type of failure.
.sp
.LP
Upon successful completion, \fBpapiJobGetAttributeList()\fR returns a pointer
to the requested data. Otherwise, it returns \fINULL\fR.
