Going from an std::thread to the related pthread

In Linux, I need to check if an address belongs to the stack of the thread or not. I have found that pthread_attr_getstack works for the purpose.

I presume that std::thread is based on pthreads, and so from my std::thread I may find a pthread and use it along with pthread_attr_getstack in order to check if the pointer points inside the stack. Is that possible? How?

std::thread::native_handle: Returns the implementation defined underlying thread handle.

See more here: http://en.cppreference.com/w/cpp/thread/thread/native_handle

Having obtained native_handle (and reasonably believing your implementation is based on pthreads, as it might not be!) you can pass this handle to any pthread routines your heart desires.
