Improving event timers?
|
I want to evaluate my new implementation of event timers, and compare its performance with the one I have (2.0.29) for different usage patterns. Three questions about add_timer, init_timer, del_timer: - I want to know how existing apps (x,tcp/ip,ppp,latex, etc) use event timers. Can I just trace some syscall using strace (which ones?)? The alternative would be instrumenting the kernel to keep track of the calls, that would take me more time coding. - are these primitives C library wrappers around system calls that do the same, or does the C part implement more functionality on top of the kernel part? - which library contains the primitives for C? gcc can't compile because the linker can't find add_timer, ... I tried to find where they are with "nm", but they don't seem to be in any file in my/usr/lib. Should I download another library from some internet site? Thanks a lot, Guillermo bodomo@hotmail.com |
