Hi, I am a little confused, I have been looking in at kern_sysctl.c, and kern_newsysctl.c in the kern folder of the xnu darwin source to understand how kernel_sysctl(......) works. and in both files it is defined there, so which kernel_sysctl is the one that my KEXT project is going to use, I am assuming kernel_sysctl in the kern_newsysctl.c since it has new in it. What if I want to use the old one, cause it seems that the kernel_sysctl in the old one would work, right now kernel_sysctl is always returning error 2, ENOENT.
