我尝试将结构作为参数传递。
全局结构:
struct ThreadParams
{
HWND window;
LIB::ServiceContainer* mrt;
};
在主线程中:
ThreadParams threadparams;
threadparams.window = (HWND) GetSafeHwnd();
threadparams.mrt = m_rt;
CWinThread* pthread1;
pthread1 = (CWinThread*) AfxBeginThread(Thread1,(LPVOID)&threadparams,THREAD_PRIORITY_NORMAL,0,0,0);
课外:
UINT Thread1(LPVOID lp)
{
ThreadParams* threadparams = (ThreadParams*) lp;
HWND hmainWindow = threadparams->window;
LIB::ServiceContainer* m_rt = threadparams->mrt;
}
尽管它可以很好地编译,但是在运行时出现错误(这是意外错误),并且我猜想我弄乱了指针m_rt。您是否看到任何明显的错误?
最佳答案
ThreadParams threadparams;
请注意,如果它是一个局部变量,并且声明它的函数在创建线程后返回,则该线程引用的对象不再存在,因为该函数返回时,局部变量将被销毁。如果是这种情况,请使用
new
创建新实例,如下所示:ThreadParams * pthreadparams = new ThreadParams();
并将其传递给线程,以便即使创建线程的函数返回也将存在。当然,完成后,您必须手动删除它。
