首先必須包含標頭檔windows.h
下面是一個簡單的例子:在主函數中開啟新的子線程執行函數f()。
#include <windows.h>
#include <iostream>
using namespace std;
void WINAPI f1(LPVOID pvThread)
{
while (true)
{
printf("inside thread 1/n");
Sleep(1000);
}
}
void WINAPI f2(LPVOID pvThread)
{
while (true)
{
printf("inside thread 2/n");
Sleep(2000);
}
}
int main()
{
HANDLE hThread1 = CreateThread(NULL,0,(LPTHREAD_START_ROUTINE)f1,NULL,0,NULL);
HANDLE hThread2 = CreateThread(NULL,0,(LPTHREAD_START_ROUTINE)f2,NULL,0,NULL);
if(hThread1 != NULL)
{
WaitForSingleObject(hThread1, INFINITE);
CloseHandle(hThread1);
}
if(hThread2 != NULL)
{
WaitForSingleObject(hThread2, INFINITE);
CloseHandle(hThread2);
}
return 0;
}
其中
if(hThread != NULL)
{
WaitForSingleObject(hThread, INFINITE);
CloseHandle(hThread);
}
這一段很重要,這段讓主線程保持住。如果沒有這段的話,執行完上一句,主線程不等子線程執行就退出,從而子線程也跟著退出了,就達不到效果。
