L_PrnGetRemoteData

#include "Ltprinter.h"

L_LTPRINTER_API L_INT L_PrnGetRemoteData(pszPrinterName, nJobId, pJobData)

L_TCHAR * pszPrinterName;	/* printer name */
L_INT nJobId;	/* job ID */
PRNJOBDATA *pJobData;	/* pointer to structure */

Obtains the remote data attached to the print Job ID.

Parameter	Description
pszPrinterName	Character string that contains the printer name.
nJobId	ID of the job to retrieve remote data.
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.
