The ScheduleJob function requests that the print spooler schedule a specified print job for printing.
BOOL ScheduleJob(
| HANDLE hPrinter, | // specifies printer for the print job |
| DWORD dwJobID | // print job identifier |
| ); |
Parameters
hPrinter
Handle that specifies a printer for the print job. This must be a local printer that is configured as a spooled printer. If hPrinter is a handle to a remote printer connection, or if the printer is configured for direct printing, the ScheduleJob function fails.
hPrinter must be the same printer handle specifed in the call to AddJob that obtained the dwJobID print job identifer.
dwJobID
Specifies the print job to be scheduled. You obtain this print job identifer by calling the AddJob function.
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
Remarks
You obtain a printer handle by calling the OpenPrinter function.
You must successfully call the AddJob function before calling the ScheduleJob function. AddJob obtains the print job identifer that you pass to ScheduleJob as dwJobID. Both calls must use the same value for hPrinter.
The ScheduleJob function checks for a valid spool file. If there is an invalid spool file, or if it is empty, ScheduleJob deletes both the spool file and the corresponding print job entry in the print spooler.
