Look at the help page (to see that it is not part of the returned  
object) and then look at the code (to see that the object returned  
from the .C() call is immediately checked to see if the number of  
iterations exceeded the maximum set by the user. Search for this code:

if (Z$iter > iter.max)

Then you should be able to see your way forward. You can either create  
a modified return object or you can insert a line that prints that  
value.
