单线程

DWORD WINAPI ThreadFunc01(LPVOID pM)
{
while (1)
{
cout << "子线程的ID为 ： " << GetCurrentThreadId() << endl;
Sleep(500);
}
return 0;
}

HANDLE hThread;
hThread = CreateThread(NULL, 0, ThreadFunc01, NULL, 0, NULL);
WaitForSingleObject( hThread, INFINITE );

多线程

HANDLE hThread[10];
for (int i = 0; i < 10; i++)
{
h[i] = CreateThread(NULL, 0, ThreadFunc01, NULL, 0, NULL);
}
WaitForMultipleObjects( 10, h, TRUE, INFINITE );

_beginthreadex

unsigned int __stdcall ThreadFunc00(PVOID pM)
{
static int num = 0;
cout << "子线程的ID为 ： " << GetCurrentThreadId() << ", num : " << num++ << endl;
return 0;
}

HANDLE h[10];

for (int j = 0; j < 10; j++)
{
h[j] = (HANDLE)_beginthreadex(NULL, 0, ThreadFunc00, NULL, 0, NULL);
}
WaitForMultipleObjects( 10, h, TRUE, INFINITE );
