Great link. Thanks. We are working on a commercial Linux based music
product. We have strong Windows/Mac skills, but are still learning in
the Linux environment. This list is a helpful place to lurk... %)
One particular issue that was mentioned on those pages was that timing
is not very accurate (dependent on HZ?) in 2.4 kernels, with great
improvments in 2.5/2.6 revs.
I am using clock_gettime(CLOCK_REALTIME) from the librt.so library. I
get values that are finer grained than HZ. Are they for real? Or perhaps
just random?
What big improvements are going on with timing in 2.5/6?
Thanks for any help.... mo
