Where can I find a description of const types in c++/com?

Question

C++ / C#

Dear users, help me understand the essence and purpose of data types (I used Google, but I could not find anything intelligible):
LPDATAOBJECT
LPCITEMIDLIST

Answer 1

Look in the section "Pointers" on the website www.codenet.ru/db/vfp/winapi
In your case:
LPDATAOBJECT - a pointer to some object
LPCITEMIDLIST - a pointer to a constant list from ITEMID

Answer 2

You are probably right and I did not quite correctly ask the question. Let me explain the essence: I am trying to write an extension for Windows Explorer (using COM), in the example I found, such types / macros are used. I would like to know what these macros are

Answer 3

If your code using these macros compiles, then their definitions are present on your system. Why not just search for them with grep, for example?

Answer 4

I advise you to study the IDE you are using. Each has its own parser, with its help go to the definition of the method / macro / function
