I'm afraid there's no clean way to get data passed to your kext at load time (and mixing in libkern C++ with a non-I/O Kit kext is problematic, but it can be done). Feel free to file an enhancement request for the feature you need, and I'll add it to my list. It seems pretty reasonable, after all! (By the way, the kmod_info_t struct contains fields for your kext's bundle ID and version, and other internal bookkeeping stuff. Nothing much of use to kexts themselves. Check out Kernel.framework/Headers/ mach/kmod.h for the definition.) Will this work as well for an NKE? Most of where I see documentation for this is for IO kit drivers... I know that using the kernel control mechanisms are the "approved" way of getting parameters to an NKE, but I'd like to set a couple of parameters which can be used in a failure condition - when the userspace application is *not* available. const OSNumber *numObject = OSDynamicCast(OSNumber, dict- >getObject("parameterName")); if (numObject) value = numObject->unsigned32BitValue(); Does anyone have sample code which reads from the registry? (I'm pretty new at kernel development...) The usual way to pass info to a driver on load is via the dictionary stored in the Info.plist file. The kext loader will copy the data items to the registry and the driver can read it from there. I have noticed that kernel modules (I'm specifically working on a socket filter NKE) have parameters passed to their MODULE_START and MODULE_STOP functions. a kmod_info_t * structure and a void *. What do these parameters represent? Is there a way for me to specify data that gets passed to my module on load? If so, how do I set that up? Pointers to documentation would be appreciated as well. I wasn't able to find what I was looking for. -Nathan _______________________________________________ Do not post admin requests to the list. They will be ignored.

I say "depending on type of development", since if you are only doing command line development, then it is easy to provide a work area without obstructing the main user, and I have already done that for a developer, though proving UI access requires that the main user is not needing the current to use their system at that point in time. While I haven't personally tried this, the manual for OSXvnc (http://www.redstonesoftware.com/products/vine/server/index.html) mentions it supports multiple simultaneous GUI logins. One for each user. Sounds like the basic idea is that each user must be logged in at the same time with Fast User Switching enabled. Then the OS X gui still operates, and thus VNC, even though the user might be in the background and not the active GUI session. -- -Corey O'Connor _______________________________________________ Do not post admin requests to the list.

You can't do Carbon or Cocoa development, but CoreFoundation is (nearly) there, along with the BSD layer, NetInfo, launchd, configd and so forth. I believe the issue has been settled, but with all due respect: Unless you are an impoverished hobbyist(1), I doubt it is worth the time and effort - legal issues aside - to do either Darwin or Mac development on a machine other than a Mac. "Get a Mac" from eBay, a G3 fshould be able to run Tiger (10.4), and a G4 will probably support Leopard (10.5). Or, do the right thing and get an Intel Mac an throw your old PC out ;) That sounds like a good solution. I know my parent's old iMac SE (the graphite coloured one) ran Jaguar without any problems (never got round to upgrading to Tiger for them). If the local university has Macs, maybe they may know a place to get second hand Macs locally. This email sent to site_archiver(a)lists.apple.com
