Hi, when using the librados c library, the documentation of the different functions just tells that it returns a negative error code on failure, e.g. the rados_read function (http://ceph.com/docs/master/rados/api/librados/#rados_read). Is there anywhere any further documentation which error code is returned under which condition and how to know _why_ the operation has failed? Thanks!
