Re: can not set up wrapper for module: nimclient

Hello,

The C code you found is correct as far as I can tell. The "!= 0" condition 
that comes first is checking that the communication worked, not checking 
the actual response code which is set in the response variable which is an 
Rlist and we get the api_version from the first entry in that list.

I will look more at this now and get back with more ideas/suggestions.
