Solution For Buffered Communication With Child Process

[brightprogrammer]

Programs that use buffered I/O (don't disable buffering) can result in a deadlock with a parent process trying to read/write data from/to the child process stdout/stdin.

There are solutions that can make the child process think it's writing to a terminal, and as a result make the I/O unbuffered.

Find a cross platform solution for Linux, Windows and Mac and implement so we have more robust control.

Example scenario of deadlock:

• child writes

• child waits for input

• parent tried to read what child wrote to stdout and then write back based on what it read

In this case if child I/O is buffered then it's possible that it does not flush and parent and child both keep waiting (deadlock)
