IPC-1: Signal echo

Requirements

• Write a C++ program that prints its PID and registers a signal handler for SIGUSR1.
• The handler of the signal SIGUSR1 is suppose to react by printing the following information:
  • The PID of the sender process,
  • The UID and the user name of the sender,
  • The current values of the EIP, EAX, EBX registers.
• Program should enter an infinite loop and perform a sleeping delay on each iteration (example: sleep for 10 seconds).

Expected result

The resulting application should be able to build and execute from command line as follows:

make
./signal-echo

Then, once any other process sends SIGUSR1 signal to our process, it should print the following information:

Received a SIGUSR1 signal from process [PID] executed by [UID] ([username]).
State of the context: EIP = [value of EIP], EAX = [value of EAX], EBX = [value of EBX]. 

The final solution should contain a Makefile for the multi-stage build. The Makefile should also contain targets all and clean. It’s recommended to have compiler and compiler flags to be declared as a Makefile variables. Alternatively, cmake could also be used instead of make.
