Hi, This must be a FAQ, but I can not find it. :-( What/were is the receipe to add new system calls. I'd like to add my own sysctl_* calls. Are there any directives on what "design" to use while defining these calls. Like: - Use only one syscall as a multiplexer (Which created a not so trivial mess is the current sysctl) - What parameters are a bad idea to transfer from user to kernel space? And answers to questions like: - Where can I find the "user"-data - Hoe to I return results for "call-by-ref" parameters Sounds like there should be at least some info on this. --WjW -- Internet Access Eindhoven BV., voice: +31-40-2 393 393, data: +31-40-2 606 606 P.O. 928, 5600 AX Eindhoven, The Netherlands Full Internet connectivity for only fl 12.95 a month.
