STL 写法

#include <thread>
#include <iostream>
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 <iostream>
#include <windows.h>
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 <pthread.h>
#include <iostream>
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;
