title: blocking/non-blocking timer in C
body: <p>This might be an often repeated question, sorry for bringing it back again. I was unable to find a solution :( . I am writing a VM monitoring code in C in Linux. I want to get the read and write count of all the VM's every 10 seconds. Is there any C library that provides this feature(timer alone), blocking/non-blocking timer doesn't matter. Thanks !!</p>
