windows - 在 DllMain 中，是否可以在没有 DLL_THREAD_ATTACH 的情况下发生 DLL_THREAD_DETACH？

Question

如果在我的 DLL 加载之前线程已经创建。然后，线程在我的 DLL 卸载之前退出。问题是:

我的 DllMain 将收到 DLL_THREAD_DETACH 通知，还是没有关于退出线程的通知？

感谢提前。

Answer 1

您会收到通知。它明确记录在 MSDN article 中对于 DllMain:

There are cases in which the entry-point function is called for a terminating thread even if the entry-point function was never called with DLL_THREAD_ATTACH for the thread:

• The thread was the initial thread in the process, so the system called the entry-point function with the DLL_PROCESS_ATTACH value.
  
• The thread was already running when a call to the LoadLibrary function was made, so the system never called the entry-point function for it.
