Parameters

L_TCHAR * pszPrinterName

Character string that contains the printer's name.

L_INT nJobId

ID of the job to retrieve remote data.

PRNJOBDATA *pJobData

Pointer to a PRNJOBDATA structure to be updated with the remote data.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

The L_PrnGetRemoteData function will obtain the pJobData structure data that was sent from the client machine printer driver, after the callback function L_PrnClntPrintJob was faired at the job is being printed.
