LPTSTR is a pointer type, a pointer to a string, or an array of TCHAR to be precise.
Depending of implementation, it can point to a ANSI or Unicode string.

You must not use LPTSTR * because it is a pointer itself:

typedef TCHAR * LPCTSTR;

Sorry, there is a typo:

LPTSTR is equivalent in fact to:
typedef TCHAR *LPTSTR;

And LPCTSTR (constant pointer) is equivalent to:
typedef const TCHAR * LPCTSTR;
