I have a question,

After polling the stdin for data using the select() function, is it as easy
as using the getchar() function to retrive the data select() has told me
was there?

Also, when using getchar(), am I allowed to just loop, reading characters
into a string, until getting an EOF?

Thanks in advance.

It's not a good idea to mix stdio functions and Unix I/O system calls.
Stdio is buffered, so select() may wait even though there's data sitting in
the stdio input buffer that could be read.

So if you need to use select() to wait for input, you should use read()
rather than getchar().

Of course, why wouldn't you be?
