I have read this discussion which discuss about how to check the signal actions of each process:
How can I check what signals a process is listening to?
However, I want to use C/C++, Python or other ways to get the userspace of the signal handler name of each process. Just like the psig in Solaris:
What is the meaning of every column when executing psig command?
Would it be possible to do that in Linux?

The signal function returns a pointer to the existing handler, if any. You can set a signal to a known value, get the existing handler's address and restore it.

I just want to know how to get the handler's name, such as termsig_sighandler in this discussion: unix.stackexchange.com/questions/163573/…
