in my multithraded application, I'm using a sleep() function (the one from the GLFW library):

```
glfwSleep(..);

```

and it apparently leads my application to segfaulting as my call stack shows:

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

```

The `glfwSleep()` is used inside a thread. Is that dangerous? Why is my program segfaulting as a consequence to that?

### Edit:

When the parameter of the `glfwSleep()` is < 0.02 (secs) it doesn't segfault!

### Edit 2:

From the official documentation of GLFW :

I think i got my answer..have to find an alternative now..

Thanks!
