R_IO
====

IO       - manages basic IO
DESC     - file descriptor (stores seek, io_handler, ..)
HANDLE   - determines io backend by io plugins
SECTION  - allows virtual base addressing over the IO
MAP      - allows virtual maps at random address

// TODO:
  - Can share storage
UNDO     - records all write ops allowing undo, redo, reset operations
  r_io_undo_*
CACHE    - caches write operations to emulate fake reads
  r_io_cache_*

-------------------------------------------

NOTES: each plugin handle must provide a 'optimal' read size.. or io must be configured to this

var io = new Radare.Io();
int fd = io.open("/bin/ls");

foreach (Io.Plugin handle in io.handle_list()) {
   stdout.printf(" %s\n", handle.name);
}
