win32 - WaitForMultipleObjects的使用

Posted 2020-12-18 strive-sun

创建5个线程，并无限期地打印某些内容

#include <Windows.h>
#include <stdio.h>

DWORD IDs[5];

DWORD WINAPI ThreadProc(LPVOID TID) {
    //expected this block to run infinitely.
    while (1) {
        printf("Inside Thread: %d. 
", TID);
        Sleep(1000);
    }

    return 0;
}

#define NBOFTHREADS 5

int main() {
    HANDLE lpHandles[NBOFTHREADS];

    for (int i = 0; i < NBOFTHREADS; i++) {
        HANDLE Threadhandle = CreateThread(0, 0, ThreadProc, &IDs[i], 0, &IDs[i]);
        printf("Thread %d -> ID %d started. 
", i, IDs[i]);
        lpHandles[i] = Threadhandle;
    }

    WaitForMultipleObjects(NBOFTHREADS, lpHandles, TRUE, INFINITE);
    return 0;
}
