This library implements a simple in-memory filesystem for Fuchsia.
It currently has no settings. Because it uses the C allocator, it can expand to fill all available memory and the max size values from POSIX statvfs()
and FIDL fuchsia.io.Node.QueryFilesystem()
may not have much meaning.
Typical in-tree C++ users should depend on //src/storage/memfs:cpp
and #include "src/storage/memfs/scoped_memfs.h"
.
// Use a separate message loop to avoid deadlock on shutdown. The loop should // enclose the memfs lifetime. async::Loop loop(kAsyncLoopConfigNoAttachToCurrentThread); loop.StartThread(); zx::status<ScopedMemfs> memfs = ScopedMemfs::CreateMountedAt(loop.dispatcher(), "/my_tmp");
Out-of-tree and C users should depend on //src/storage/memfs
and #include <lib/memfs/memfs.h>
.
