named-pipe-ipc

Golang parent/child process IPC via named pipes

What does it do

Once process_executor executable is ran, it launches spawned_process executable and then it listens for messages from named pipe. The spawned_process process sends one message via named pipe. Those messages are received by process_executor process which prints them to console.

How to use it

• make build compiles all executable into bin directory
• make run runs process_executor which in turn runs spawned_process

Sample execution

Note, logs prefixed with timestamp are from process_executor, the others are from spawned_process.
