ipc-app

Project agenda

Project is consist of two applications: parent and child. When the parent process starts, it also starts the child process and observes the state of child application. When child executable is terminated or crashed, it's immediately executed by parent application

Full task conditions you can find in taskConditions.pdf file in the materials/ folder of this project

How to test

1. Compile child subproject:
   • cd child/
   • mkdir build(!!this name is obligatory and hardcoded inside this version of application!!)
   • cd build/
   • cmake ..
   • cmake --build .
2. Compile and execute parent subproject:
   • cd parent/
   • mkdir build(!!this name is obligatory and hardcoded inside this version of application!!)
   • cd build/
   • cmake ..
   • cmake --build .
   • ./parent

After parent process is executed, you can input the period of counter in child process(from 1ms to 1000ms). When number is entered you'll see the value of counter printed in stdout every second. The value of counter depends on period you entered.

Now you maybe want to kill the child process by open one more terminal and write kill <pid>, where <pid> is PID of child process(can be obtained by ps -ef command). After child process is killed, new process will be started by parent application.
