示例1: if
std::cv_status
wait_until_impl(
mutex &lock,
const std::chrono::time_point<Clock, Duration> &abs_timeout)
{
PMEMobjpool *pop = pmemobj_pool_by_ptr(this);
/* convert to my clock */
const typename Clock::time_point their_now = Clock::now();
const clock_type::time_point my_now = clock_type::now();
const auto delta = abs_timeout - their_now;
const auto my_rel = my_now + delta;
struct timespec ts = detail::timepoint_to_timespec(my_rel);
auto ret = pmemobj_cond_timedwait(pop, &this->pcond,
lock.native_handle(), &ts);
if (ret == 0)
return std::cv_status::no_timeout;
else if (ret == ETIMEDOUT)
return std::cv_status::timeout;
else
throw lock_error(ret, std::system_category(),
"Error waiting on a condition "
"variable.");
}示例2:
void
condition::wait(mutex &m)
{
pthread_mutex_t* the_mutex = m.native_handle();
int const res = pthread_cond_wait(&c, the_mutex);
if (res) boost::throw_exception(
boost::thread_resource_error(res, "pthread_cond_wait failed"));
}示例3: lock_error
/**
* Internal implementation of the wait call.
*/
void
wait_impl(mutex &lock)
{
PMEMobjpool *pop = pmemobj_pool_by_ptr(this);
if (int ret = pmemobj_cond_wait(pop, &this->pcond,
