Your userland program uses a kernel control socket file descriptor to communicate with your kernel control module. A kernel control socket file descriptor is above all a file descriptor so you can use a kernel control socket file descriptor userland API that work with socket file descriptors. To avoid to poll you can for example use select() or CFSocket for this with a call back function. I have an NKE that I currently have registered using ctl_register function and from my userland I connect to the NKE using sockets, that is calling socket(PF_SYSTEM, SOCK_DGRM, SYSPROTO_CONTROL) then on success connect(). What I would like to do is be able for the NKE to signal or notify the app when it has some something to do or send, without the app going into a constant loop waiting for data via a recv() function. Someone had mentioned the possibility of using CFSocket for this with a call back function. I am not sure if this possible using a NKE and that is my question. Can my idea be done using CFSocket and if yes are there any examples of this using a kext? Of if not any other suggestions? _______________________________________________ Do not post admin requests to the list. They will be ignored.
