If any process has more than one child processes, then after calling wait(), parent process has to be in wait state if no child terminates.
If only one child process is terminated, then return a wait() returns process ID of the terminated child process.
If more than one child processes are terminated than wait() reap any arbitrarily child and return a process ID of that child process.
When wait() returns they also define exit status (which tells our, a process why terminated) via pointer, If status are not NULL.
If any process has no child process then wait() returns immediately “-1”.
NOTE: “This codes does not run in simple IDE because of environmental problem so use terminal for run the code”

I've done this on QNX4.5 that doesn't support threads or Boost by using select . You basically pass select STDIN as the file descriptor to use and select will return when a new line is entered. I've added a simplified example loop below. It's platform independent, at least for Unix like systems. Not sure about Windows though. here

I would do this by creating separate a thread which calls normal blocking IO functions and pass it a callback function which it would call when it got input. Are you sure you need to do what you said you want to do? more

Ans: do console IO on a background thread and provide a means of communicating between threads. here

What's the best/easiest way to do this? I have no problem using external libraries like boost, as long as they use a permissive license. more
