[rrd-developers] Re: Wnat to use rrd into C

Hey Henrik (and everyone else),

Thanks for the example and info.  I have a few questions about it though.

By using the C API directly, I have to link against librrd.  This
means that any such code that I write must be released under a
GPL-compatible license.  Correct?

Does calcpr have to be freed later if the call to rrd_graph was
successful?  I don't see that in your example or in hobbitgraph.c
(which this example is very similar to).

Any incite would be much appreciated.
