Something i've just learned within the past few chapters of my book is 
that you can pass arrays, and arrays of pointers to functions. You can 
also pass structures, and (i believe) unions (just about to read the 
chapter on unions) to functions.
These all deal with holding more than one piece of data within a 'tag' 
name. Dont forget to double dereference ('**') when prototyping a 
function that has an array of pointers passed to it. I spent a few hours 
chasing a bug in my program, only to find out I left out an asterisk. I 
must say i'm a bit jealous in hearing you're over half way through your 
book that you just started reading. Its been a few months and i'm ~%75 
through mine.

Best regards,
Rob.
