22.214.171.124.4 RpcRouterReplyPrinterEx (Opnum 66)
DWORD RpcRouterReplyPrinterEx( [in] PRINTER_HANDLE hNotify, [in] DWORD dwColor, [in] DWORD fdwFlags, [out] DWORD* pdwResult, [in] DWORD dwReplyType, [in, switch_is(dwReplyType)] RPC_V2_UREPLY_PRINTER Reply );
dwColor: The value that was most recently specified by the client in the dwColor parameter of a call to RpcRouterRefreshPrinterChangeNotification (section 126.96.36.199.5).
fdwFlags: A value that contains Printer Change Flags (section 188.8.131.52), which indicate changes in printer configuration values.
pdwResult: A pointer to a value that contains Change Notification Flags (section 184.108.40.206), which indicate how the client processed the notification.
dwReplyType: A value that MUST be zero.
Reply: A pointer to an RPC_V2_UREPLY_PRINTER union, which contains a pointer to an RPC_V2_NOTIFY_INFO structure, which contains available notification data that matched the set of notifications that the client previously requested.
Return Values: This method MUST return zero (ERROR_SUCCESS) to indicate successful completion or a nonzero Windows error code to indicate failure, as specified in [MS-ERREF].
Upon receiving this message, the print client MUST validate parameters as follows:
Verify that the hNotify parameter is an RPC context handle to a notification object that was opened using RpcReplyOpenPrinter, and if that verification fails, return ERROR_INVALID_HANDLE, as specified in [MS-ERREF]. This method SHOULD assume that this handle can be used without further access checks.
Verify that the value of the dwColor parameter matches the last value that was passed in the dwColor parameter in the call to RpcRouterRefreshPrinterChangeNotification; if that verification fails, set the PRINTER_NOTIFY_INFO_COLORMISMATCH bit in the variable pointed to by pdwResult and return 0.
If parameter validation fails, the client MUST fail the operation immediately and return a nonzero error response to the server. Otherwise, the client MUST process the message as follows:
Capture the fdwFlags in the notification state it maintains.
Capture the notification data provided in the Reply parameter in the notification state.
Store the result of processing the notification (Change Notification Flags) to the variable pointed to by pdwResult.
