8.13 setitimer: Setting Interval Timers. The setitimer system call is a generalization of the alarm call. It schedules the delivery of a signal at some point in the future after a fixed amount of time has elapsed. A program can set three different types of timers with setitimer:. If the timer code is ITIMER_REAL, the process is sent a SIGALRM signal after the specified wall-clock time has elapsed.

DESCRIPTION. The sigaction() function allows the calling process to examine and/or specify the action to be associated with a specific signal.The argument sig specifies the signal; acceptable values are defined in .. The structure sigaction, used to describe an action to be taken, is defined in the header to include at least the following members: 24.3.5 Flags for sigaction. The sa_flags member of the sigaction structure is a catch-all for special features. Most of the time, SA_RESTART is a good value to use for this field. The value of sa_flags is interpreted as a bit mask. Thus, you should choose the flags you want to set, OR those flags together, and store the result in the sa_flags member of your sigaction structure.
