From 9065006ccbe0a94e9536950f389a0cbc3dfb4dda Mon Sep 17 00:00:00 2001 From: Paul Eggert Date: Mon, 20 Sep 2010 15:44:31 -0700 Subject: sort: destroy spin locks portably * src/sort.c (sortlines, sort): Use pthread_spin_destroy when a spin lock is no longer used. This isn't needed on GNU/Linux or Solaris, but POSIX says it may free up resources on some platforms. --- src/sort.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/src/sort.c b/src/sort.c index a8d0c142b..89f7be32c 100644 --- a/src/sort.c +++ b/src/sort.c @@ -3480,6 +3480,8 @@ sortlines (struct line *restrict lines, struct line *restrict dest, queue_insert (merge_queue, &node); merge_loop (merge_queue, total_lines, tfp, temp_output); } + + pthread_spin_destroy (&lock); } /* Scan through FILES[NTEMPS ..
