What is the meaning of every column when executing psig command?

Question

I try to use psig command to track signal dispositions of a process on Solaris:

bash-3.2# psig 3109
3109:   bash
HUP     caught  termsig_sighandler      0       HUP,INT,ILL,TRAP,ABRT,EMT,FPE,BUS,SEGV,SYS,PIPE,ALRM,TERM,USR1,USR2,VTALRM,XCPU,XFSZ,LOST
INT     caught  0x80c0e88       0
QUIT    ignored

What are the exact meanings of every column? I try to find it in Oracle psig document, but can't find the detail meanings of every column.

@NanXiao - you should've have cross-posted it, you should've flagged this Q for migration to that site. Please delete this one and I can reopen the U&L one afterwards. — slm, Oct 22 '14 at 06:33
While current Solaris source isn't available, this output hasn't changed in many years, so you can reference the source code in the final OpenSolaris snapshot - specifically psig.c. — alanc, Oct 22 '14 at 06:35
@NanXiao - no problem, you didn't know. I've flagged this for migration now. — slm, Oct 22 '14 at 06:38

The first column mean the signal that is sent. Use kill -l for a list of all signal that are available on your system (see the oracle documentation for the meaning of the signals, here the most important ones).

The second column indicates whether the signal is caught by a signal handler of the process or not. caught means that there is a signal handler assiciated to the signal. Note that some signals can't be caught by the process (SIGKILL, SIGSTOP). Others are ignored. That means the process didn't react to the signal.

The third column is the userspace address of the handler.

The fourth column: The sa_flags: Special flags to affect behavior of signal. See the different flags and their meanings

The fifth column: A list of signals to be blocked when the handler is executed.
