Hi,

The "how to write a block" GNU Radio guide is an awesome guide to 
understanding this:
http://www.gnu.org/software/gnuradio/doc/howto-write-a-block.html

Then you will understand what "input_items" is... it's not what you were 
told :P  Whatever "plain old data" might actually be.

The quick answer is that it's a stream of arrays, where there can be a 
single stream which is what you want (a single array).  But read the 
guide to completely understand it.

Aside from that, you don't typically call the work() function yourself. 
 You connect the blocks and as data is streamed through your flow 
graph, the work() function is called on that stream.  Read the guide and 
you will understand this.
