线程休眠代码(C++)

linux平台示例：

/*

*/
#include 
#include 
#include 
void m_threadSleep(int sec,int nsec)
{
struct timespec sleepTime;
struct timespec returnTime;
    sleepTime.tv_sec = sec;
    sleepTime.tv_nsec = nsec;
    nanosleep(&sleepTime, &returnTime);
}
void test1()
{
    m_threadSleep(1,0);
    printf("I'm thread1 ...\r\n");
}
void test2()
{
    m_threadSleep(2,0);
    printf("I'm thread2 ...\r\n");
}
int main()
{
    pthread_t thread1,thread2;
void *result;
    time_t tbegin,tend;
    tbegin = time(NULL);
    pthread_create(&thread1,NULL,(void*)&test1,NULL);
    pthread_create(&thread2,NULL,(void*)&test2,NULL);
    pthread_join(thread1,&result);
    pthread_join(thread2,&result);
    tend = time(NULL);
    printf("%d\r\n",tend-tbegin);
return 0;
}

编译：
gcc thread1.c -o thread1 -lpthread

boost库实现示例：

/*
File      : boost_thread1.cpp
Author    : Mike
E-Mail    : [email protected]
*/
#include 
#include 
#include 

boost::xtime getSleepTime(int sec,int nsec)
{
    boost::xtime t;
    boost::xtime_get(&t, boost::TIME_UTC);
    t.sec += sec;
    t.nsec += nsec;
return t;
}
void test1()
{
    boost::this_thread::sleep(getSleepTime(1,500));
    std::cout <<"I'm thread1 !"<< std::endl;
}
void test2()
{
    boost::this_thread::sleep(getSleepTime(3,500));
    std::cout <<"I'm thread2 !"<< std::endl;
}

int main(int argc, char* argv[])
{
    boost::thread thrd1(&test1);
    boost::thread thrd2(&test2);
    std::time_t t_begin,t_end;
    t_begin = time(NULL);
    thrd1.join();
    thrd2.join();
    t_end = time(NULL);
    std::cout<return 0;
}

编译命令：
g++ boost_thread1.cpp -o boost_thread1 -lboost_thread-mt
