From 269f21344b23e552c21c9e2d7ca258479dcd7a0a Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Sat, 3 May 2008 15:28:45 -0400 Subject: [PATCH] tiny mq_open optimization A very small cleanup for mq_open. We do not have to call set_close_on_exit if we create the file descriptor right away with the flag set. We have a function for this now. The resulting code is smaller and a tiny bit faster.
