[rrd-users] getting MAX, LAST VDEFs without generating graph from C library

I have some existing rrdfile with some data in them.
I was reading about the VDEF capabilities of the rrdgraph
I am using the c library functions to manipulate the rrd files.
I want the MAX and LAST from a graph, but I don't want the graph.
At the command line I would do:
rrdtool graph xy.png -aPNG
This prints to stdout.
If I am calling rrd_graph() C function, how do I get this data?
Is there a better way to do this? I m very open to suggestions, but I
have to stick with the C library calls.
Ok, one more question:
I dont see any API docs for theC library on the web site. Are there any?
Reminder: I am at GMT+2, 10 hours AHEAD of Seattle.
My workweek is Sunday-Thursday.
Email sent to me Thursday afternoon (PST) may not be viewed until Sunday
