It happens that on Linux timer_t is void *, so both that change and this commit are no-ops there, but not on systems where timer_t is not void *. Using timer_ptr2id for filling sival_ptr also does not make sense since that actually is a void *. * sysdeps/pthread/posix-timer.h (timer_ptr2id): Cast to timer_t instead of void *. * sysdeps/pthread/timer_create.c (timer_create): Do not use timer_ptr2id to cast struct timer_node * to void *. --- ChangeLog | 4 ++++ sysdeps/pthread/posix-timer.h | 2 +- sysdeps/pthread/timer_create.c | 2 +- 3 files changed, 6 insertions(+), 2 deletions(-) diff --git a/ChangeLog b/ChangeLog index f2a771781e..497b00f65a 100644 --- a/ChangeLog +++ b/ChangeLog @@ -13,6 +13,10 @@ return 0. * sysdeps/mach/hurd/dl-sysdep.c (_dl_sysdep_start): Cast vm_address_t * to ElfW(Addr) * for dl_main parameter. + * sysdeps/pthread/posix-timer.h (timer_ptr2id): Cast to timer_t + instead of void *. + * sysdeps/pthread/timer_create.c (timer_create): Do not use + timer_ptr2id to cast struct timer_node * to void *. 2018-01-27 James Clarke diff --git a/sysdeps/pthread/posix-timer.h b/sysdeps/pthread/posix-timer.h index 82311706d8..d7af9a017a 100644 --- a/sysdeps/pthread/posix-timer.h +++ b/sysdeps/pthread/posix-timer.h @@ -87,7 +87,7 @@ extern struct thread_node __timer_signal_thread_rclk; /* Return pointer to timer structure corresponding to ID. */ #define timer_id2ptr(timerid) ((struct timer_node *) timerid) -#define timer_ptr2id(timerid) ((void *) timerid) +#define timer_ptr2id(timerid) ((timer_t) timerid) /* Check whether timer is valid; global mutex must be held. */ static inline int diff --git a/sysdeps/pthread/timer_create.c b/sysdeps/pthread/timer_create.c index 1c80e6162f..2381a60d6f 100644 --- a/sysdeps/pthread/timer_create.c +++ b/sysdeps/pthread/timer_create.c @@ -77,7 +77,7 @@ timer_create (clockid_t clock_id, struct sigevent *evp, timer_t *timerid) { newtimer->event.sigev_notify = SIGEV_SIGNAL; newtimer->event.sigev_signo = SIGALRM; - newtimer->event.sigev_value.sival_ptr = timer_ptr2id (newtimer); + newtimer->event.sigev_value.sival_ptr = newtimer; newtimer->event.sigev_notify_function = 0; }
