创建10个线程并发执行（STL/Windows/Linux）

C++并发编程入门 目录

STL 写法

#include 
#include 
using namespace std;
 
void thread_fun(int arg)
{
    cout << "one STL thread " << arg << " !" << endl;
}
 
int main(void)
{
    int thread_count = 10;
    int id_array[10] = { 1,2,3,4,5,6,7,8,9,10 };
 
    std::thread thread_arr[10] = { };
 
    for (int i = 0; i < thread_count; i++)
    {
        thread_arr[i] = std::thread(thread_fun, id_array[i]);
    }
 
    for (int i = 0; i < thread_count; i++)
    {
        thread_arr[i].join();
    }
 
    return 0;
}

Windows 写法

#include 
#include 
using namespace std;
 
DWORD WINAPI ThreadFun(LPVOID lpParamter)
{
    //转成整数地址，再对地址解引用取出整数
    cout << "one Windows thread "<< *(int*)lpParamter<<" !" << endl;
    return 0;
}
 
int main()
{
    int thread_count = 10;
    HANDLE handleArr[10] = {NULL};
    //给线程函数传递的数据，用来标记线程
    int data[10] = { 1,2,3,4,5,6,7,8,9,10 };
    for (int i = 0; i < 10; i++)
    {
        handleArr[i] = CreateThread(NULL, 0, ThreadFun, &data[i], 0, NULL);
    }
 
    //等待10个线程结束
    WaitForMultipleObjects(thread_count, handleArr, TRUE, INFINITE);
 
    for (int i = 0; i < thread_count; i++)
    {
        CloseHandle(handleArr[i]);
    }
 
    return 0;
}

 

Linux 写法

#include 
#include 
using namespace std;
 
void* thread_fun(void *arg)
{
    cout << "one Linux thread "<< *(int*)arg<<" !" << endl;
    return 0;
}
 
int main(void)
{
    int thread_count = 10;
    int id_array[10] = { 1,2,3,4,5,6,7,8,9,10 };
    pthread_t thread_arr[10] = { 0 };
 
    for (int i = 0; i < thread_count; ++i)
    {
        pthread_create(&thread_arr[i], NULL, thread_fun, &id_array[i]);
    }
 
    //让线程运行直到结束
    for (int i = 0; i < thread_count; i++)
    {
        pthread_join(thread_arr[i], NULL);
    }
 
    return 0;
}
