RpcDeletePrinterDriver removes the specified printer driver from the list of supported drivers for a server.

 DWORD RpcDeletePrinterDriver(
   [in, string, unique] STRING_HANDLE pName,
   [in, string] wchar_t* pEnvironment,
   [in, string] wchar_t* pDriverName
 );

pName: Specified in Print Server Name Parameters (section 3.1.4.1.4).

pEnvironment: Specified in Environment Name Parameters (section 3.1.4.1.3).

pDriverName: A pointer to a string that specifies the name of the printer driver to delete. For rules governing printer driver names, see section 2.2.4.3.

Return Values: This method MUST return zero (ERROR_SUCCESS) to indicate successful completion or a nonzero Windows error code to indicate failure [MS-ERREF].

Upon receiving this message, the server MUST validate parameters as follows:

• Perform the validation steps that are specified in Print Server Name Parameters.

• Perform the validation steps that are specified in Environment Name Parameters.

• Verify that the string pointed to by the pDriverName parameter contains the name of a driver that is part of the list of drivers that are installed on the server for the environment specified by the string pointed to by the pEnvironment parameter; if that verification fails, return ERROR_UNKNOWN_PRINTER_DRIVER.

• Verify that the printer driver is not used by any printer in the system, and if that verification fails, return ERROR_PRINTER_DRIVER_IN_USE.

• Additional validation MAY<333> be performed.

If parameter validation fails, the server MUST fail the operation immediately and return a nonzero error response to the client. Otherwise, the server MUST process the message and compose a response to the client as follows:

• Clear all references to this printer driver from any other data structures.

• Delete the printer driver object.

• If any clients have registered for notifications of the server object change, a notification MUST be broadcast to them.

• Return the status of the operation.
