Detailed Description

A filesystem-like object is one that can be used to open file-like objects though it by fopen("/name/filename", mode)

Implementations must define at least open (the default definitions of the rest of the functions just return error values).

Note:
Synchronization level: Set by subclass

Definition at line 43 of file FileSystemHandle.h.
