多线程编译测试 

#include <boost/thread.hpp>
#include<iostream>
int main()
{
    std::cout
    <<boost::thread::hardware_concurrency()
    <<'\n'
    <<boost::thread::physical_concurrency()
    <<'\n';
    return 0;
}
/*
g++ -o 20191118.o 20191118.c -l boost_thread -l boost_system -l pthread
*/




线程锁 

boost::mutex mtx
void my_thread()
{
....
boost::lock_guard<boost::mutex>lock(mtx);    //lock_guard在构造函数里加锁，在析构函数里解锁。
....
}

共享内存编译测试 

#include<boost/interprocess/shared_memory_object.hpp> 
#include<iostream>
int main()
{
    boost::interprocess::shared_memory_object shdmem(boost::interprocess::open_or_create,"Highscore",boost::interprocess::read_write);
    shdmem.truncate(1024);
    boost::interprocess::offset_t size;
    if(shdmem.get_size(size))std::cout<<size<<'\n';
    return 0;
}
/*
g++ -o test.o test.c -l rt
*/
