We are trying to make the new APIs (such as the SFTP AIO) in a way that it should be ready to work in async mode. But as far as I know, all the old ones will have to be rewritten. Some functions might need just internal changes (the simple one returning int/ssize_t, for example sftp_fsync()), but others will likely need a new API as they return now an object (such as sftp_new()), where it is not possible to return SSH_AGAIN while waiting for the response. We have a abandoned draft for the change of sftp_new() and sftp_init() to work with non-blocking mode here: https://gitlab.com/libssh/libssh-mirror/-/merge_requests/404/ Jakub
