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.

          How many registers does an x86_64 CPU actually have?

          Image
          Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
