WaitForSingleObject的用法

一般用来线程（或者类似线程机制）的同步

 

 // TODO: Add your control notification handler code here
 CEvent obj;
 obj.SetEvent();
 DWORD a = WaitForSingleObject(obj.m_hObject,100);
 
 CString str;
 str.Format(L"%x",a); ///0表示等到了，成功

 this->MessageBox(str);

 

 

 

 // TODO: Add your control notification handler code here
 CEvent obj;

obj.ResetEvent();//这句话可加，可不加

 DWORD a = WaitForSingleObject(obj.m_hObject,100);
 
 CString str;
 str.Format(L"%x",a); /// 102表示Timeout，失败

 this->MessageBox(str);
