The devices use DMA, so I am planning not to implement the scatter/gather I/O functionality of the "readv" and "writev" system calls for these drivers. Can anyone tell me if this will break Unix? I cannot find any examples of utilities or systems that use readv/writev now, so do not believe that it should make much difference. Dave Cobbley Tektronix, Inc.
