PS.: You query remind me of a "nice surprise" when i was working with timer on linux
Regarding the timer resolution, refer to time(7) in the man pages. Looks like the resolution can be configured from kernel 2.6.13 onwards. A snippet:
"since kernel 2.6.13, the HZ value is a kernel configuration parameter and can be 100, 250 (the default) or 1000, yielding a jiffies value of, respectively, 0.01, 0.004, or 0.001 seconds."

Hi,
I have a main loop which calls a sub loop, which finally returns to the main loop itself. The main loop runs when a flag is set. Now, I have a signal handler for SIGINT, which resets the flag and thus stops the main loop. Suppose I send SIGINT while the program is in subloop, I get an error... (1 Reply)
