So I've tested it on a OpenSuse machine. And there it behaves a little bit different. Instead of finishing there will be raised a segmentation fault. Here is the sample output for UPPER_BOUND = 500000000 and 500 ms intveral:

Does anyone has a good source, which explains, what happens inside the OS, when a context is swapped or a signal is raised? I didn't find anything on the web... :/

Hello all,
I am starting to learn signal handling in Linux and have been trying out some simple codes to deal with SIGALRM. The code shown below sets a timer to count down. When the timer is finished a SIGALRM is produced. The handler for the signal just increments a variable called count. This... (7 Replies)
