After looking around the net I came across a presentation, which had a bit of information on it and what appears to be a code example. But I can not make heads nor tails of it.

Okay, thanks. How do I find out for what file descriptor the signal is related to and what event has happened. I am looking around for a complete example but have been unable to find one.

Does anyone know of any good references on using SIGIO. I have searched around but have been able to find very little on the subject. I have taken a look at the fcntl man page which gives a bit of...

It is a well known fact that a common enemy to all evil people is whitespace, as it is the one thing that stands between well obfuscated code. :p

I really do like your object orientated approach,...

Thank you very much. It all seems to work fine now! In the end I came up with this function (which works perfectly) and would like to know if you have any suggestions for how it could be improved:

I did not use fgets as I do not know how much they will type. It could be up to (and if redirecting stdin) over 10k.
I used the number 32 because, well, it seemed like a reasonable number to...

Recently I need a way to read a line from stdin, but it was quite important that I read the entire line (as some of the inputs were quite large). So I decided to have a go at writing a function, that...

I needed to make some wrappers for some functions in my program as my argument structure was different to that of the lib/functions that I had created. It has been suggested that the best way to do...

When calculating very large factorials you might want to use Stirling's approximation (which is much faster), http://en.wikipedia.org/wiki/Stirling%27s_approximation . To do 5! you would do:
