int nghttp2_session_check_request_allowed(nghttp2_session *session)

Returns nonzero if new request can be sent from local endpoint.

This function return 0 if request is not allowed for this session. There are several reasons why request is not allowed. Some of the reasons are: session is server; stream ID has been spent; GOAWAY has been sent or received.

The application can call nghttp2_submit_request2() without consulting this function. In that case, nghttp2_submit_request2() may return error. Or, request is failed to sent, and nghttp2_on_stream_close_callback is called.
