[已解决]C++关于互斥锁问题

我这个是有加互斥锁的吧，为什么还这样输出？

// 定义互斥锁句柄
HANDLE g_hAndle1 = 0;
DWORD CALLBACK threadShow0111(LPVOID lpParameter)
{
const char* p1 = (const char*)lpParameter;
while (1)
{
// 等待互斥资源
WaitForSingleObject(g_hAndle1, INFINITE);
for (int i = 0; i < strlen(p1); i++)
{
printf("%c", (char*)p1[i]);
Sleep(125);
}
printf("\n");
// 释放互斥锁
ReleaseMutex(g_hAndle1);
}
}
DWORD CALLBACK threadShow0211(LPVOID lpParameter)
{
while (1)
{
const char* p1 = (const char*)lpParameter;
while (1)
{
// 等待互斥资源
WaitForSingleObject(g_hAndle1, INFINITE);
for (int i = 0; i < strlen(p1); i++)
{
printf("%c", (char*)p1[i]);
Sleep(125);
}
printf("\n");
// 释放互斥锁
ReleaseMutex(g_hAndle1);
}
}
}
int main()
{
// 2. 创建互斥锁
g_hAndle1 = OpenMutex(NULL, FALSE, NULL);
DWORD mId;
HANDLE hread01 = CreateThread(NULL, 0, threadShow0111, (void*)"********", 0, &mId);
HANDLE hread02 = CreateThread(NULL, 0, threadShow0211, (void*)"--------", 0, &mId);
getchar();
// 关闭互斥锁
CloseHandle(g_hAndle1);
return 0;
}
