FileDescriptor

struct FileDescriptor

File descriptor.

The intention is to manage the life-time of a file descriptor almost as if it was a std::unique_ptr disallowing inadverent copying and ensuring the automatic release of resources.

The are however no strong guarantees: it is just too easy to access and copy the real file descriptor (the integer).
