[Click] Writing your own element

[Ian Rose]

Could you say a bit more about how you want this element to work - I'm 
afraid I'm not really getting the full picture.  Perhaps an example of 
how a packet should be handled would help.  And when you say that the 
receive "is not working out", what do you mean?  Are packets never 
received by your element?  It might help to put a Print element right 
before your element (in your click configuration) - this element will 
Print some stuff to the console every time a packet flows through it, so 
if nothing is ever printed then you know that packets simply aren't 
moving and it might be a problem with your click config itself (in which 
case, send it in an email so we can take a look).

Also, what does your elements 'processing' method return?  Just look in 
<yourelement>.hh and you should see something like:

const char *processing() const	{ return PUSH; }

or

const char *processing() const	{ return AGNOSTIC; }

If you don't see a processing method then you are using the default 
(AGNOSTIC).
