What is the proper or best practice method for the kernel
to notify a user level process (or processes) of an event.
This event may possibly have data. The processes may or may
not exist. The event is generated by some arbitrary kernel
event (a counter, a call being made, etc.)
Typically I have seen this done as file I/O via a device.
syslogd is a program that fits this description. A special
device '/dev/klog' was provided for it.
What is the best practice these days?
Please reply to me directly, I will summarize the results
to the list.
