[Xcb] Xcb errors

[Matthew Allen]

Is there a list of the error codes that can be returned in xcb_generic_error_t::error_code?

I'm getting the error '2' back from a xcb_create_window_checked call. Where I give the screen's root as the parent, and I've set override redirect to true (it's a popup window). I'll keep playing with the parameters in the meantime but some help with looking up errors would be good.
