Get the address of the screen ( most likely from firmware, ) calculate the size of the screen and then rip it via firewire. A basic idea of how to write the ripping code can be found here, <ftp://ftp.AnarchistTurtle.com/Others/Quinn/Hacks/ FireStarter1.0a1.sit>, this actually pushes things to the screen but the read should be trivial. Once this is done, you will then have to write a quick app to convert your raw grab into a jpeg or gif. I did something similar a while back but not from ">console", but firewire will be up so it should work. This email sent to site_archiver(a)lists.apple.com

Re: Multiple Bluetooth Adapters per host -- will they work

I am working on a command-line bluetooth application, and my customer recently asked an intriguing question. He would like to be able to connect multiple bluetooth adapters to a darwin-based system in order to effectively increase the bandwidth available for bluetooth communication. I am writing to see if anybody has tried something similar. It is not clear to me if the Bluetooth API will handle the associated multihoming of multiple bluetooth adapters or not. Any thoughts are appreciated. Regards, -Mike Ellis ========================= Michael F.

Instead, our application is designed to communicate with lots of individual bluetooth devices. On a per connection basis, the actual bandwidth requirements are quite low. Our intention is to create a central bluetooth server that is capable of managing lots of slow connections. We would like to add the extra adapter to effectively double the number of clients that the server can simultaneously support. So I suppose my question is: "Will Darwin's kernel-level bluetooth support take advantage of the extra bluetooth adapter in order to effectively double the number of bluetooth devices that can be simultaneously supported?" There is nothing in the Bluetooth spec for multiplexing one data stream over two Bluetooth radios, and the API follow the spec pretty closely. You didn't say what you need the extra bandwidth for, and I assume it is not networking. If it is a custom designed device, you can do this, but synchronizing the data between two separate stacks would be up to your software and the device. _______________________________________________ This email sent to site_archiver(a)lists.apple.com

Difference between .comm and .globl + .zerofill

Maybe someone here knows the answer? What is the practical difference between the following two (assembler) declarations, apart from the fact that the former cannot be used in dynamic libraries and the latter can be? (because in one case the data resides in the text section and in the other in the data section). Is there a reason not to always use the latter form?
