LPHANDLE vs HANDLE

While looking at the code, I found an OpenPrinter () call . The code compiles and works fine. But we pass HANDLEinstead LPHANDLE(as indicated on MSDN). I found out that the windef.hfollowing declaration exists:

typedef HANDLE FAR          *LPHANDLE;

What does LP mean? Should I use LPHANDLEor save HANDLE?

LP stands for Long Pointer. This is a pointer to a descriptor in this case.

HANDLE h = <winapi function>();
LPHANDLE ph = &h;

You can use it just like a pointer descriptor descriptor:

HANDLE anotherh = *ph;
or
<winapi function>(*ph, ...);

"LP" means "Long Pointer".

HANDLE! = LPHANDLE, same as DWORD! = DWORD * (or LPDWORD)
