kqueue

Hello. Recently I started looking into kqueue(2), and to get to know the interface better I attempted to turn usr.sbin/moused into a kqueue program (replacing the main select() loop that reads the mouse device). Now I thought I understood the interface, I requested a kqueue, but as soon as I

kqueue and filenames

Hi, I'm using kqueue for detecting file-events; for additional information I add a struct to udata, when registering an event with kevent. When I delete an event, will be udata deleted too, or do I have to manage the memory for the structs with an own implementation? kevent is triggered

Thanks for your reply! Am 23.01.2012 20:12, schrieb Pieter de Goeje: kevent is triggered when a file is renamed. How do I get the new name? Is there an extra function? In the moment, I see only the possibility by searching the filesystem(folder) for a new name. A good question to which I unfort

KQueue and EVFILT_TIMER question

Hi, I'm using a kqueue(2) that installs a timer into the queue when a certain condition has happened. This timer waits for another condition at intervals (specifically, it watches for a file to be created). Every 500ms it does a stat(2) for a given filename and when stat succeeds, I d

kqueue + EVFILT_TIMER unreliable timing problems

Hi everyone, I'm trying to use kqueue with EVFILT_TIMER to create an interval timer. However, I'm getting very unreliable results. The code for a test case is at: http://pastebin.com/ratK0AXL I'm finding that regardless of the number of ticks I wait for, it takes around 50%

Using kqueue with 2 threads

Hi, I'm trying to use a kqueue to listen for VNODE events on a worker thread. I want new events to be registered with the kqueue by a separate thread. I have been referring to this example [URL=" http://doc.geoffgarside.co.uk/kqueue/file.html";] http://doc.geoffgarside.co.uk/k

Re: Using kqueue with 2 threads

t; std::endl; }[/CODE] Did i understand right, that after registering and firing one event the kevent() function doesn't block any more? If so, register the events with EV_ADD | EV_CLEAR. With this flag, the event state is cleared and kevent() is still blocking(man kqueue). That

kqueue and polling ... are they related?

Re: kqueue and polling ... are they related?

None of these have any relation to polling of the network interfaces as described in the polling(4) manpage. The only connection between poll(2) and polling(4) is that they have similar names. So, to answer your question: No, you do not need to have polling enabled in order to use kqueue
