From 0a949ebdf0b9fc054ea868bd049c8f2c7aed973e Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Thu, 10 Mar 2011 10:43:09 -0500 Subject: [PATCH] don't fail with EINTR in sigtimedwait POSIX allows either behavior, but sigwait is not allowed to fail with EINTR, so the retry loop would have to be in one or the other anyway. --- src/signal/sigtimedwait.c | 12 ++++++------ 1 file changed, 6 insertions(+), 6 deletions(-) diff --git a/src/signal/sigtimedwait.c b/src/signal/sigtimedwait.c index 155185de..0a7c5eac 100644 --- a/src/signal/sigtimedwait.c +++ b/src/signal/sigtimedwait.c @@ -1,12 +1,12 @@ #include +#include #include "syscall.h" int sigtimedwait(const sigset_t *mask, siginfo_t *si, const struct timespec *timeout) { - long k_timeout[2]; - if (timeout) { - k_timeout[0] = timeout->tv_sec; - k_timeout[1] = timeout->tv_nsec; - } - return syscall4(__NR_rt_sigtimedwait, (long)mask, (long)si, timeout ?
