GetPrinterDriverDirectory function

The GetPrinterDriverDirectory function retrieves the path of the printer-driver directory.


BOOL GetPrinterDriverDirectory(
  _In_  LPTSTR  pName,
  _In_  LPTSTR  pEnvironment,
  _In_  DWORD   Level,
  _Out_ LPBYTE  pDriverDirectory,
  _In_  DWORD   cbBuf,
  _Out_ LPDWORD pcbNeeded


pName [in]

A pointer to a null-terminated string that specifies the name of the server on which the printer driver resides. If this parameter is NULL, the local driver-directory path is retrieved.

pEnvironment [in]

A pointer to a null-terminated string that specifies the environment (for example, Windows x86, Windows IA64, or Windows x64). If this parameter is NULL, the current environment of the calling application and client machine (not of the destination application and print server) is used.

Level [in]

The structure level. This value must be 1.

pDriverDirectory [out]

A pointer to a buffer that receives the path.

cbBuf [in]

The size of the buffer to which pDriverDirectory points.

pcbNeeded [out]

A pointer to a value that specifies the number of bytes copied if the function succeeds, or the number of bytes required if cbBuf is too small.

Return value

If the function succeeds, the return value is a nonzero value.

If the function fails, the return value is zero.



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.
