Low level C++ "structure"?
<p>This will admittedly be tricky to phrase, but I am trying to find out what other low-level C++ "structures" are there?</p>

<p>I am thinking of things similar to the virtual table, which help C++ to actually perform the duties it does. I presume the VTable only handles certain tasks (like storing function signatures) and is only used for certain aspects of the language (like overloading, overriding etc).</p>

<p>Is there any "structure" used for multithreading/keeping track of threads/objects or is that all done by the OS?</p>
