Writing own blocks

Hi everyone

I need to write a custom block or two. I went through the tutorial on
the gnuradio website. This only outlines the basics. What I want to
do is to implement a polyphase filterbank channeliser that takes in an
input stream an breaks it up into a number of channels. I should then
be able to select the channel that I want by passing it as a parameter
to the new block in a gnuradio application. Does anyone have any
recommendations on code that I can look at to help me? How does
history in filters work in gnuradio blocks?

Thanks a lot.
