I am not completely new to the darwin underpinnings, but I have
been assigned a task that definitely requires pretty good knowledge
of the mach kernel. First I'd like to ask what's a good
introduction to the kernel (let's call it a crash course).
Next I'd like to explain what I need to be able to do. I basically
need to be able to detect when someone is reading from a shared
resource (in this case the display buffer). For what I understand,
any such resources are arbitrated through mach ports. If a process
needs access to one, it obtains either read or write rights to it
(multiple reader, single writer?), and then is able to access the
resource. Is this correct? If so, I should be able to determine
when someone obtains read access to such a port via the kernel
trace facility or something similar. At least that's my idea.
Perhaps I am wayyyyyyy off. Feel free to let me know if that's so
or if I am oversimplifying things.
This is probably the best you'll be able to do.

Excellent book. Best reference outside of reading the source code.
