Well, technically, 99.9% of the userbase will be (linux|*BSD)/x86, so it would only "trash" a potential 0.099% ;-) > In the Linux world the > ioctl32 handlers munge the structures.

Dont think of it as "trashing", think of it as "an opportunity to get rid of 'munging'" :-) > I believe DaveM's DRM for the sparc64 linux is quite happy with > mixed 32/64 user space. Probably it has the same size for "unsigned long" in both 32 and 64 bit modes. "It works" is not the same as "it works cleanly". APIs should be fixed, concrete definitions. The struct definitions in drm.h are essentially part of the API (or ABI, whatever), and they are not fixed. They should be cleaned up. ------------------------------------------------------- This SF.net email is sponsored by: Etnus, makers of TotalView, The debugger for complex code.
