[Click] cpElement

[Koen Segers]

Where can I find the exact meaning of cpElement as used in the configure 
method? I made a design where every element is configured with this 
information element. But I suspect the element is copied, although I want in 
every element a pointer to only 1 element (pointer). 

Right now I have coded it this way:
In my header:
PDHCPInfo* _info;

In the configure method:
if (cp_va_parse(conf, this, errh, cpElement, "PDHCPInfo", &_info, cpEnd) <0)  
etc...

I saw in the click documentation that cpElement results in a pointer to 
pointer. Therefore I use the & (it also doesn't compile without one).
