Hi, everyone. I'm a newbie to mac kernel.
Recently I decided to develop a kext to support interprocess communication.
Let's say a user-space program sending operation string to kext.
And kext received the message and reply corresponding result to user-space program.
Given a real life example is that, a user-space program sending "bus_speed" to kext.
When kext received the message, it sending the bus speed result of current machine back to user-space program.
Which it's a full-round communication.
Can anyone here figure out what mechanism should I use to do this job?
What communication mechanism should best suit in such case?
Thanks all you guys.
:-D
