HTimer in Linux (High resolution timer)

Question

Does somebody has any idea of HT Timer in Linux? I will be glad if someone shares some code snippets with examples of how to implement the same.

Thanks in advance

Answer 1

Depends on your application type.

For event-driven applications your event notification library (like libevent) should provide timer scheduling functionality.

There is also POSIX timer_create() function, that can deliver timer expiry as a signal or a callback in another thread. Latest Linux provides timerfd mechanism to deliver timer expirations through a regular file descriptor that can be registered with select()/poll()/epoll().

Answer 2

Here similar question with sample code for clock_gettime().
