Hi all,

Since this flavor of question has been cropping up lately, it may be time to reiterate a point about kernel programming interfaces.

If a function is not in Kernel.framework/Headers/, you can't use it in a kernel extension. And, if a function is defined for kernel use only, you can't use it in user space.

Now back to our regular scheduled email.

Hi folks

I have an existing kext that needs to be modified slightly to look at
process information. The process information I need is performed elsewhere
by calling 'sysctl' ala:

mib[0] = CTL_KERN;
mib[1] = KERN_PROC;
mib[2] = KERN_PROC_ALL;
error = sysctl(mib, 3, procInfo, &buffersize, NULL, NULL);

This code works fine in the user land application, but now I want to do the
same in the kext. It doesn't appear that I can directly call 'sysctl' from
a kext, so can anyone help me determine the proper way of retrieving this
information? Advice is greatly appreciated.

thanks,
Chris
