我正在开发一个多线程系统,这是我的代码类演示在 .h 文件中定义
当主函数的循环第二次执行时,下面的 COMMENT1 将采用前一个值
关闭句柄不会关闭线程吗?
int threadentry(void* data)
{
demo* inst=(demo*) data;
cout << "Value of inst "<<hex << &inst<< endl;
string request;
cin>>request;
if(request==play)
{
inst->play;
cout << "Value of inst "<<hex << &inst<< endl;
// COMMENT1 here when the thread is executed second time from the main it is taking previous value
}
}
int main()
{
while(1)
{
demo* inst=new demo();
cout << "Value of inst "<<hex << &inst<< endl; //value is coming different from above
HANDLE threads;
DWORD threadId1;
if ((threads = CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)threadentry,
(void *)inst, 0, &threadId1)) == NULL)
return -1;
//here is some Processing of data and after processing I close the handle
CloseHandle(threads);
delete inst;
system("pause");
}
}
