Yes, si_signo will match sig. Which siginfo_t fields are interesting to record can vary by signal (i.e. by si_code). si_code and si_errno are certainly the first things that come to mind as most useful. For SI_TIMER, si_tid, si_overrun, and si_sigval are interesting. For others, si_pid and si_uid are interesting.
Thanks, Roland
