Off hand I don't know of anything written in C++ that is or could be a user
of gfapi.
Never the less, it's possible that one could exist, or be written, and
marking the library entry points is a) friendly, b) possibly allows the
C++ compiler to generate better code, and c) is a good practice when
writing APIs that might be consumed by C++ applications. Considering we
already take the first step and use __BEGIN_DECLS/__END_DECLS to be C++
friendly, we should take the extra step

There is an ongoing effort to integrate NFS Ganesha (
https://github.com/nfs-ganesha/nfs-ganesha/wiki ) with GlusterFS as one of
the file system back ends.
Towards this we need extensions to gfapi that can handle object based
operations. Meaning, instead of using full paths or relative paths from
cwd, it is required that we can work with APIs, like the *at POSIX
variants, to be able to create, lookup, open etc. files and directories.
Hence the objects are the files or directories themselves and we give out
handles to these objects that can be used for further operations.
This code drop is an initial implementation of the proposed APIs.
The new APIs are implemented as glfs_h_XXX variants in the file
glfs-handleops.c to mirror glfs-fops.c style. The code leverages holding
onto inode references and doling these out as opaque/cookie type objects to
the callers, to enable them to be used as handles in other operations.
An fd based approach was considered, but due to the extra footprint that
the fd structure and its counterparts would incur, this was dropped to take
the approach of holding inode references themselves.
Tested by extending glfsxmp.c to invoke and exercise the added APIs, and
further tested with a reference integration of the same as an FSAL with NFS
Ganesha.
