I have complete control over the application (I guess, other than the speed with which I can convert it to fully native :) I can pre-change in application space, or post-change in my kext - doesn't make much difference AFAICT. Obviously I have to convert somewhere, as the data block is opaque (known to my app and kext, but not to kernel or Rosetta). So I know that's a task I have to do, but I just need a connection. Could you put an intermediate process into the user-space pipe chain which would dynamically change the byte-order of your messages? Obviously, you would only want it to run where the PPC app is on Intel. This is a really big deal. I have an app which will move only slowly to native, rather than "real soon now". Converting the kext was already on my list, but not the whole app! Is there a way we can have the ioctl code handled, and let us deal with the parameters?? Even a new ioctl, so that there aren't compatibility issues with existing apps? One of the challenges here is that on Intel, your kext is running little endian. Your user space process is running in big endian in Rosetta. For many common ioctls, there is code, I believe in Rosetta, to translate the ioctl code itself as well as parameters from big endian to little endian. The CTLIOGINFO ioctl for the SYSPROTO_CONTROL protocol is not supported. Were it supported, the kext would have to determine the byte order of the client since the kernel can not know the format of data passed between the user space process and the kext. In addition to making your kext a universal binary, you also need to make the client that talks to your kext a universal binary. Is communication from allowed from an app running in Rosetta to an intel NKE? I have a fat NKE installed. I seem to be able to communicate to it to some extent when my app is running under intel, but when my app runs under PPC I get an exeception. /* open socket to NKE*/ if( (sock = socket(PF_SYSTEM, SOCK_STREAM, SYSPROTO_CONTROL)) == -1) RETERR(kPGPError_ResourceUnavailable); and when making the ioctl, my app dies with SIGILL "Unhandled transform (1) for ioctl group = 78 (N), number = 3, length = 100" Vinnie Moscaritolo ITCB- IMSH PGP: 3F903472C3AF622D5D918D9BD8B100090B3EF042 ------------------------------------------------------- _______________________________________________ Do not post admin requests to the list.
