According to the documentation it makes sense if it would return zero in case previous libssh2 calls did *not* return LIBSSH2_ERROR_EAGAIN. The purpose of libssh2_session_block_directions() is to learn what libssh2 wants to do next, in which direction it wants data. If you call the function when there is no pending data then 0 makes sense to me. Doing so isn't strictly an error but possibly broken logic in your client..? //Peter -- libssh2-devel mailing list libssh2-devel@lists.haxx.se https://lists.haxx.se/listinfo/libssh2-devel
