ResGuard – tiny C++ RAII wrapper

This single-header library gives you a drop-in RAII guard for anything that needs to be released.
File descriptors, sockets, mutexes, malloc’d memory, CUDA handles, Win32 objects, … you name it.

Why?

• No more forgotten close, free, ReleaseMutex, etc.
• No accidental double-free or resource leak.
• Works exactly like std::unique_ptr, but for non-pointer resources.
