Class Netfs.empty_fs

class empty_fs : string -> stream_fs

This is a class where all methods fail with ENOSYS. The string argument is the detail in the Unix_error, normally the module name of the user of this class.

empty_fs is intended as base class for implementations of stream_fs outside Ocamlnet. When stream_fs is extended by new methods, these methods are at least defined, and no build error occurs. So the definition should look like

      class my_fs ... =
          inherit Netfs.empty_fs "my_fs"

          method read flags name = ...

          (* Add here all methods you can define, and omit the rest *)
