From fdf5f1b13123883ac1d5e298e5f32c7ed43578ce Mon Sep 17 00:00:00 2001 From: Bobby Bingham Date: Thu, 6 Feb 2014 22:11:22 -0600 Subject: clone: make clone a wrapper around __clone The architecture-specific assembly versions of clone did not set errno on failure, which is inconsistent with glibc. __clone still returns the error via its return value, and clone is now a wrapper that sets errno as needed. The public clone has also been moved to src/linux, as it's not directly related to the pthreads API. __clone is called by pthread_create, which does not report errors via errno. Though not strictly necessary, it's nice to avoid clobbering errno here. --- src/thread/clone.c | 7 ++----- 1 file changed, 2 insertions(+), 5 deletions(-) (limited to 'src/thread/clone.c') diff --git a/src/thread/clone.c b/src/thread/clone.c index 339e28a3..be80c8ea 100644 --- a/src/thread/clone.c +++ b/src/thread/clone.c @@ -1,10 +1,7 @@ #include -#include "libc.h" +#include "pthread_impl.h" int __clone(int (*func)(void *), void *stack, int flags, void *arg, ...) { - errno = ENOSYS; - return -1; + return -ENOSYS; } - -weak_alias(__clone, clone); -- cgit 1.4.1
