Be cautious here - a bus address is 64bits on some builds of x86-32 kernels. Only virtual addresses are 32bit limited. Also don't forget that you run 32bit apps on 64bit platforms. Linux uses __u32/__u64/__s32/__s64 to be specific about such types and to make it easier to build ioctls that don't need magic translation glue ------------------------------------------------------- This SF.Net email is sponsored by BEA Weblogic Workshop FREE Java Enterprise J2EE developer tools!
