C 语言在 windows 中多线程的例子

#include <windows.h>
#include <stdio.h>

DWORD WINAPI ThreadProc1(LPVOID lpParam) {

    int i = 0, j = 0;
    while (1) {
        printf("hello,this thread 1 ...\n");

        //延时
        for (i = 0; i < 200000000; i++);
    }
}

DWORD WINAPI ThreadProc2(LPVOID lpParam) {

    int i = 0, j = 0;
    while (1) {
        printf("hello,this thread 2 ...\n");

        //延时
        for (i = 0; i < 200000000; i++);
    }
}

main() {
    int i = 0;
    //创建线程1
    CreateThread(
        NULL, // default security attributes
        0, // use default stack size
        ThreadProc1, // thread function
        NULL, // argument to thread function
        0, // use default creation flags
        NULL); // returns the thread identifier

    //创建线程2
    CreateThread(
        NULL, // default security attributes
        0, // use default stack size
        ThreadProc2, // thread function
        NULL, // argument to thread function
        0, // use default creation flags
        NULL); // returns the thread identifier

    //让主线程进入循环，主线程若退出，子线程1，2会被系统“杀死”
    while (1) {
        printf("hello,this thread 0 ...\n");

        //延时
        for (i = 0; i < 200000000; i++) ;

    }
