The docs for IOLog say "IOLog should not be called from interrupt context."
However, it appears that Apple breaks this rule - in
AppleUSBOHCI_Interrupts.cpp they definitely call IOLog from PollInterrupts -
which is called from InterruptHandler. Am I missing something or is the doc
for IOLog not right? I'm porting some OS9 code to OSX. We've used DCON for
debug output in the past, I'm trying to determine of IOLog will meet our
needs as a replacement for DCON on OSX.
Thanks,
