This (C) library is called libgfapi.so and can be installed with the glusterfs-api RPM (or similar for other distributions). The interface is described in it's main header file [0] from the glusterfs-api-devel RPM. The glusterfs sources have a few examples [1] and small applications for regression testing [2][3]. There are also several projects that use the library, you cool look at those for examples as well: - glusterfs-coreutils [4] - Samba/vfs_glusterfs [5] - NFS-Ganesha/FSAL_GLUSTER [6] Under the Gluster organization in GitHub you can find bindings to different languages [7]. If you exaplain a litte more about the application that could use libgfapi for accessing Gluster, we can advise you on how we'd approach/design the access interface. Important information includes access patterns, i/o operations and muti-process/threading needs.
