Hi, can anyone tell me if there's a relation between the sleep() C function and the implementation of timers in Linux? I know there's a relation between alarm() system call and timers, as alarm() calls the kernel function settimer() that initializes real_timer field of the calling process. In this case, I can set the timer calling alarm() from user space and then, if necessary, modify the real_timer field from kernel space. In other word, I want to know if the behavior of sleep() is analogous, in order to implement such a mechanism in a simplified way. Thanks.
