I need to use sosend, and the others in the kernel so that i can communicate with my daemon in user space, so i am doing it in user space. Communicating between the kernel and user space with a UNIX domain socket is not a very good approach. Darwin has a mechanism called "User Clients", which allow an IOKit module to communicate with one or more user space processes.
