  • Article

RpcAsyncEnumPrinterDataEx enumerates all registry value names and data under the key for the specified printer.

The counterpart of this method in the Print System Remote Protocol is RpcEnumPrinterDataEx. All parameters not defined below are specified in [MS-RPRN] section 3.1.4.2.20.

 DWORD RpcAsyncEnumPrinterDataEx(
   [in] PRINTER_HANDLE hPrinter,
   [in, string] const wchar_t* pKeyName,
   [out, size_is(cbEnumValues)] unsigned char* pEnumValues,
   [in] DWORD cbEnumValues,
   [out] DWORD* pcbEnumValues,
   [out] DWORD* pnEnumValues
 );

hPrinter: A handle to a printer object that has been opened using either RpcAsyncOpenPrinter (section 3.1.4.1.1) or RpcAsyncAddPrinter (section 3.1.4.1.2).

Return Values: This method returns zero to indicate successful completion or a nonzero Win32 error code ([MS-ERREF] section 2.2) to indicate failure. Aside from the specific nonzero return values documented in section 3.1.4, the client MUST treat any nonzero return value as a fatal error.

Exceptions Thrown: This method MUST NOT throw any exceptions other than those that are thrown by the underlying RPC protocol [MS-RPCE].

This method MUST adhere to the parameter validation, processing, and response requirements that are specified in [MS-RPRN] section 3.1.4.2.20.
