string manipulation question with strcpy and strcat and alike

I have been trying to use lstrcpy and lstrcat functions to combine texts as shown below:

Code:

BOOL PDFPRNINSTCALL PdfPrnInstCopyDriverFilesW(const WCHAR* pSourceFolder)
{
	LPWSTR destFolder = L"E:\\test";
	LPWSTR SdriverPath, SconfigFilePath, SlicenseFilePath;
	LPWSTR DdriverPath, DconfigFilePath, DlicenseFilePath;
	SdriverPath = SconfigFilePath = SlicenseFilePath = L"";
	DdriverPath = DconfigFilePath = DlicenseFilePath = L"";

	// Process the filenames to include directory + filename 
	lstrcpy(SdriverPath, pSourceFolder);
	lstrcpy(DdriverPath, destFolder);

	wcout << SdriverPath << endl;
	wcout << DdriverPath << endl;

	return true;
}

However, on the output window/debugger, I'm not seeing anything that SDriverPath nor DdriverPath is holding. Is there something that I've missed before using the string manipulation functions? Thanks.

Well since you didn't allocate any memory to your string pointers before trying to copy into them, it should be crashing all over the place.

LPWSTR is not a type (string). It's a pointer. This is why I suggest avoiding using Microsoft typedefs.
A pointer must point to an allocated buffer, as well, or you will most likely get an access violation.
