From 9962e7fd037872c423544f61cba1c901b045363a Mon Sep 17 00:00:00 2001 From: guenther Date: Wed, 21 Oct 2009 16:04:23 +0000 Subject: Fix the handle locking in stdio to use flockfile/funlockfile internally when and where required. Macros in are updated to automatically call the underlying functions when the process is threaded to obtain the necessary locking. A private mutex is added to protect __sglue, the internal list of FILE handles, and another to protect the one-time initialization. Some routines in libc that use getc() change to use getc_unlocked() as they're either protected by their own lock or aren't thread-safe routines anyway. ok kurt@, earlier version tested by sthen@ and jj@ --- lib/libc/stdio/asprintf.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'lib/libc/stdio/asprintf.c') diff --git a/lib/libc/stdio/asprintf.c b/lib/libc/stdio/asprintf.c index de6404ecb4f..b3b037a1fb2 100644 --- a/lib/libc/stdio/asprintf.c +++ b/lib/libc/stdio/asprintf.c @@ -1,4 +1,4 @@ -/* $OpenBSD: asprintf.c,v 1.15 2005/10/10 12:00:52 espie Exp $ */ +/* $OpenBSD: asprintf.c,v 1.16 2009/10/21 16:04:23 guenther Exp $ */ /* * Copyright (c) 1997 Todd C.
