1.使用互斥量与事件对象实现线程同步的例子代码：

view plaincopy to clipboardprint?
#include
#include

using namespace std;

DWORD WINAPI Fun1Proc_dd(LPVOID lpParameter);
DWORD WINAPI Fun2Proc_dd(LPVOID lpParameter);

int index = 0;
int tickets_dd = 100;
HANDLE hMutex;
HANDLE hEvent;

void main_dd(int argc, char **argv)
{

HANDLE hThread1;
HANDLE hThread2;

//互斥量
/*hMutex = CreateMutex(NULL, FALSE, "test");
if (hMutex)
{
if (ERROR_ALREADY_EXISTS == GetLastError())
{
cout << "only one instance can run!" << endl;
return;
}
}*/
hEvent = CreateEvent(NULL, FALSE, TRUE, NULL);

if (hEvent)
{
if (ERROR_ALREADY_EXISTS == GetLastError())
{
cout << "Only one instance can run!" < 0)
{
Sleep(1);
cout << "thread1_dd sell ticket: " << tickets_dd-- < 0)
{
Sleep(1);
cout << "thread2_dd sell ticket: " << tickets_dd-- << endl;
SetEvent(hEvent);
}
else
{
SetEvent(hEvent);
break;
}
//ReleaseMutex(hMutex);
}

return 0;
}

2.使用关键代码段实现线程同步的例子代码：

view plaincopy to clipboardprint?
#include
#include

using namespace std;

DWORD WINAPI Fun1Proc(LPVOID lParameter);
DWORD WINAPI Fun2Proc(LPVOID lParameter);

CRITICAL_SECTION g_cs;

int tickets = 100;

int main()
{
HANDLE hThread1;
HANDLE hThread2;

hThread1 = CreateThread(NULL, 0, Fun1Proc, NULL, 0, NULL);
hThread2 = CreateThread(NULL, 0, Fun2Proc, NULL, 0, NULL);
CloseHandle(hThread1);
CloseHandle(hThread2);

//初始化关键代码段
InitializeCriticalSection(&g_cs);
Sleep(4000);
//使用完毕删除关键代码段
DeleteCriticalSection(&g_cs);

return 0;
}

DWORD WINAPI Fun1Proc(LPVOID lParameter)
{

while (TRUE)
{
//进入关键代码段，如果被人占用则一直等待
EnterCriticalSection(&g_cs);
Sleep(1);
if (tickets > 0)
{
cout << "thread1 sell ticket : " << tickets-- < 0)
{
cout << "thread2 sell ticket : " << tickets-- << endl;
LeaveCriticalSection(&g_cs);
}
else
{
LeaveCriticalSection(&g_cs);
break;
}
}
return 0;
}
