DeletePrinterDataEx function
The DeletePrinterDataEx function deletes a specified value from the configuration data for a printer. A printer's configuration data consists of a set of named and typed values stored in a hierarchy of registry keys. The function deletes a specified value under a specified key.
Like the DeletePrinterData function, DeletePrinterDataEx can delete values stored by the SetPrinterData function. In addition, DeletePrinterDataEx can delete values stored under a specified key by the SetPrinterDataEx function.
Syntax
DWORD DeletePrinterDataEx(
_In_ HANDLE hPrinter,
_In_ LPCTSTR pKeyName,
_In_ LPCTSTR pValueName
);
Parameters
-
hPrinter [in]
-
A handle to the printer for which the function deletes a value. Use the OpenPrinter or AddPrinter function to retrieve a printer handle.
-
pKeyName [in]
-
A pointer to a null-terminated string that specifies the key containing the value to delete. Use the backslash ( \ ) character as a delimiter to specify a path that has one or more subkeys.
If pKeyName is NULL or an empty string, DeletePrinterDataEx returns ERROR_INVALID_PARAMETER.
-
pValueName [in]
-
A pointer to a null-terminated string that specifies the name of the value to delete.
Return value
If the function succeeds, the return value is ERROR_SUCCESS.
If the function fails, the return value is a system error code.
Remarks
Note
This is a blocking or synchronous function and might not return immediately. How quickly this function returns depends on run-time factors such as network status, print server configuration, and printer driver implementation factors that are difficult to predict when writing an application. Calling this function from a thread that manages interaction with the user interface could make the application appear to be unresponsive.
