- Subject: adding noreturn attribute to pthread_exit
Hi,
Calling pthread_exit() at the end of a routine marked noreturn produces
a compiler warning/error on cygwin:
error: 'noreturn' function does return
Is it possible to add the attribute to the cygwin pthread.h:
--- pthread.h.orig 2012-10-19 14:40:13.000000000 +0200
+++ pthread.h 2013-01-14 21:40:00.018198900 +0100
@@ -137,7 +137,7 @@
void *(*)(void *), void *);
int pthread_detach (pthread_t);
int pthread_equal (pthread_t, pthread_t);
-void pthread_exit (void *);
+void pthread_exit (void *) __attribute__((__noreturn__));
int pthread_getcpuclockid (pthread_t, clockid_t *);
int pthread_getschedparam (pthread_t, int *, struct sched_param *);
void *pthread_getspecific (pthread_key_t);
(note, i didn't check how it needs to trickle down in the cygwin
implementation of pthread_exit())
