GetDllDirectory function

Applies to: desktop apps only

Retrieves the application-specific portion of the search path used to locate DLLs for the application.

Syntax

Copy

DWORD WINAPI GetDllDirectory(
  __in   DWORD nBufferLength,
  __out  LPTSTR lpBuffer
);

Parameters

nBufferLength [in]: The size of the output buffer, in characters.
lpBuffer [out]: A pointer to a buffer that receives the application-specific portion of the search path.

Return value

If the function succeeds, the return value is the length of the string copied to lpBuffer, in characters, not including the terminating null character. If the return value is greater than nBufferLength, it specifies the size of the buffer required for the path.

If the function fails, the return value is zero. To get extended error information, call GetLastError.
