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,
