He meant declaring glfwSetWindowCloseCallback like this:
alias extern(C) nothrow void function() callback;
extern(C) void glfwSetWindowCloseCallback(callback cb);

There's no difference in the generated code, but this way the compiler
will complain if you pass a non-nothrow function to
glfwSetWindowCloseCallback.
