parent-child-ipc

Golang parent/child process IPC via standard in/out

What does it do

Once parent executable is ran, it launches child executable and then it listens for messages from child process standard output. The child process sends three messages through its standard output. Those messages are received by parent process which prints them to console.

How to use it

  • make build compiles parent and child into bin directory
  • make run runs parent process which in turn runs child process

Sample execution

$> make run
./bin/parent
