Hi Sastry, vppcom_app_create() can return an error even if binary api attachment is successful. To check if application has successfully attached to vpp’s session layer, see “show app”. To debug vcl, set VCL_DEBUG env variable to at least 1.
Connects, if delivered by vcl to vpp, are handled in session_mq_connect_handler. Connect replies from vpp to vcl are handled by vcl because linux and vcl fds cannot be mixed. That is, when vppcom_epoll_wait is run, all pending events are handled, including connect replies.
