But I don't see similar concept in Linux. I am not sure if I have understood you correctly and I am not familiar with windows drivers, but I think what you are trying to do is wrong. You have the source code of every driver and every subsystem of the kernel. You can change the driver, subsystems, in-kernel apis, ... and create new ones whenever you like. Why do you want do add function call redirects at runtime? Such things make changing drivers or other things later much harder. It may be the only way, if you do not have the source code of the driver/kernel. On Linux, you do! -Michi -- programing a layer 3+4 network protocol for mesh networks see http://michaelblizek.twilightparadox.com -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
