Well, this code needs to read some data continously. Then the data must be processed and written to a file. If you expect problems, I could create a new syscall and pass a buffer to it. Probably this should be Ok. But the buffer can be huge (comparable with the RAM size), so I would like to avoid copying data. This means that the kernel needs to write to the userspace buffer directly. Thank you for the reply. Regards, Pavel Roskin ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
