I can do free(STRUCTPOINTER->thing1->thing2)

but I can't do free((*STRUCTPOINTER).(*thing1).thing2) (Expected identifier before ( token. For (*thing1

nor can I do free((*STRUCTPOINTER).thing1.thing2) Error, (*temporary)-> is a pointer, did you mean to use '->' ?

I am used to writing my code and referring to things in (*this).format. Is this possible for what I'm trying to do?

As I noted (more or less) in a comment:

If you're insane enough not to use the arrow notation, you would need to use:

free((*(*ptr).thing1).thing2);

I'm sorry, but I don't like shouting as loudly as STRUCTPOINTER requires, especially as it isn't a macro; I'm using ptr instead.

• *ptr is the structure that ptr points to
• (*ptr).thing1 is the member of the structure, which is a pointer to a structure, so you need
• *(*ptr).thing1 to dereference the structure, and
• (*(*ptr).thing1).thing2 to access the element

The arrow notation was invented for a good reason — this is it! It is hard to get the alternative correct.
