示例1: Threadpool
Threadpool(unsigned thrd_cnt, const std::function<void(unsigned inst)>& f) : _f(f) {
unsigned cores = boost::thread::hardware_concurrency();
Logger::pLOG->info("Found {} cores for DOR", cores);
if (thrd_cnt == 0 || thrd_cnt > cores)
thrd_cnt = cores;
for (unsigned i = 0; i < thrd_cnt; ++i) {
boost::thread* t = _tg.create_thread([this, i](){ Threadpool::_f(i); });
//The thread name is a meaningful C language string, whose length is
//restricted to 16 characters, including the terminating null byte ('\0')
std::string s = "DOR-THRD-" + std::to_string(i);
Logger::pLOG->info("Created {}", s);
#ifdef __linux__
if (pthread_setname_np(t->native_handle(), s.data()))
Logger::pLOG->warn("Could not set name for {}", s);
struct sched_param param {};
param.sched_priority = RT_PRIO;
if (pthread_setschedparam(t->native_handle(), SCHED_FIFO, ¶m))
Logger::pLOG->warn("Could not set realtime parameter for {}", s);
#endif
}
Logger::pLOG->info("DOR has {} thread/s running", _tg.size());

void start()
{
if (m_threads.size() > 0)
{ return; }
for(ios_type& ios : m_io_services)
{
m_threads.create_thread(
boost::bind(&ios_type::run,
boost::ref(ios)));
}
}示例3: waitTermination
void waitTermination( boost::thread_group& threads, std::initializer_list< int > signals = { SIGINT, SIGTERM, SIGQUIT } )
{
sigset_t sset;
sigemptyset( &sset );
for( const auto each: signals )
{

}
sigprocmask( SIG_BLOCK, &sset, nullptr );
std::cout << "threads running: " << threads.size() << "; main thread waiting for termination signals...\n";
int sig = 0;
sigwait( &sset, &sig );
std::cout << "termination signal " << sig << " has been caught\n" << "interrupting threads...\n";
threads.interrupt_all();

{
return my_group.size();
