Yes this seems confusing as on mac+linux Long is either 32 or 64bits depending on the architecture, but this is how the X11 protocol is defined. Thus 5 is the correct value for the nelts here. Not 5 or 10 depending on the architecture. More info on the confusion https://bugs.freedesktop.org/show_bug.cgi?id=16802
