Is it possible to decompile a C++ DLL?

Hex-Rays decompiler is probably the best in this field !!! I think a C++ DLL is a machine code file. Therefore decompiling will only result in assembler code. If you can read that and create C++ from that you’re good to go.

Why do you need to reverse engineer function calls?

There are many reasons to reverse engineer the calls to internal functions of processes. For example, if you’ve ever seen any sort of game add-ons or “mods”, they may use this technique of calling a process’ (the game’s) internal functions to display text on the screen. Perhaps, you want to extend the hotkey functionality to a program.
