I grabbed a few off the internets:
- Advanced Programming in the Unix Environment, Richard W. Stevens, Chapter 5.
- this is probably the best literature on this, I hope you have access to it
via your University’s library or so. Let me know if you have trouble getting
a copy.
- http://man7.org/linux/man-pages/man3/stdio.3.html
- http://man7.org/linux/man-pages/man3/stdout.3.html
- http://c.learncodethehardway.org/book/ex24.html
- http://www.erlang.org/doc/tutorial/c_port.html
- https://nodejs.org/api/child_process.html
- https://nodejs.org/api/fs.html (especially fs.write(), fs.read() and variants)
Best
Jan
