c++ - glfwSleep() 如何导致段错误？

Question

在我的多线程应用程序中，我使用了一个 sleep() 函数(来自 GLFW 库的函数):

glfwSleep(..);

它显然导致我的应用程序出现段错误，正如我的调用堆栈所示:

#0 76CFC2BC WaitForSingleObjectEx() (C:\Windows\system32\kernel32.dll:??)
#1 00000016 ??() (??:??)
#2 0000006C ??() (??:??)
#3 00000000 ??() (??:??)

glfwSleep() 在线程内使用。那很危险吗？为什么我的程序会因此出现段错误？

编辑:

当 glfwSleep() 的参数小于 0.02(秒)时，它不会发生段错误!

摘自GLFW的官方文档:

Writing threaded applications may be very awkward before you get used to it, but there are a few key rules that are fairly simple to follow:

• ALWAYS assure exclusive access to data that is shared between threads!
• Make sure that threads are synchronized properly!
• NEVER busy wait!

我想我得到了答案..现在必须找到替代方案..

谢谢!

来自 the GLFW wiki :

GLFW doesn't work well with GHC threads, forkIO or threadDelay. So avoid them if you can.
