Data Fields
int(*	open )(void *fs, const char *path, int flags, void **file)
	Open path with open() flags; store the file handle in file.
int(*	close )(void *fs, void *file)
	Close and free a file handle.
int(*	read )(void *fs, void *file, void *buf, unsigned len)
	Read up to len bytes; 0 at end of file.
int(*	write )(void *fs, void *file, const void *buf, unsigned len)
	Write len bytes; a short count means the filesystem is full.
int(*	lseek )(void *fs, void *file, int offset, int whence)
	Move the file position; return the new position.
int(*	fstat )(void *fs, void *file, vfs_stat_t *stat)
	Report an open file's type and size.
int(*	stat )(void *fs, const char *path, vfs_stat_t *stat)
	Report a path's type and size; ENOENT if it does not exist.
int(*	mkdir )(void *fs, const char *path)
	Create a directory whose parent exists.
int(*	rmdir )(void *fs, const char *path)
	Remove an empty directory.
int(*	unlink )(void *fs, const char *path)
	Remove a closed regular file.
int(*	list )(void *fs, const char *path, vfs_directory_visitor_t visitor, void *context)
	Call visitor for each entry of a directory, as vfs_list() does.
