Where were you when we decided to switch to C++ ? :-) On a more serious note, as I've explained, the *style* comes from a best practice rule in C++. This obviously makes no difference whatsoever in C, nor does it in C++ for integer types, it's only a matter of consistency with the rest of the driver. -- Regards, Laurent Pinchart
