From mboxrd@z Thu Jan 1 00:00:00 1970 From: Yevgeny Kliteynik Subject: opensm/main.c: foce stdout to be line-buffered Date: Wed, 03 Mar 2010 10:26:46 +0200 Message-ID: <4B8E1D46.4090106@dev.mellanox.co.il> Mime-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit Return-path: Sender: linux-rdma-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: Sasha Khapyorsky Cc: Linux RDMA List-Id: linux-rdma@vger.kernel.org When stdout is assigned to a terminal, it is line-buffered. But when opensm's stdout is redirected to a file, stdout becomes block-buffered, which means that '\n' won't cause the buffer to be flushed. Forcing stdout to always be line-buffered.
