entity pointer as entity's member

Hi, I think I saw this question before, but I cant get to the post where it was. If someone knows where to find it can you redirect me, or answer me here please.
Can I add a pointer to another entity in an entity's skill, and how to do so? Or make an entity pointer as a member of an entity.

Or if someone thinks in a better way to do so let me know.

I mean, ptr_for_handle (handle); will do the trick or it returns a handle for all the same entities?

Thanks in advance.

my.skill1 = handle(you);
...
you = ptr_for_handle(my.skill1);

Is this what you want? ^^

ptr_for_handle(); returns a pointer, not a handle.
Same entities don't have same handles

Thanks for the help, but I dont understand handle();
does it return a specific number for every object, or it returns a number for the type of file?

Look in my edited post ^^

All right much appreciated.
