Hello, While digging more for this I've found these :
http://svn.apache.org/viewvc/thrift/lib/c_glib/test/ Which shows how to create the TSocket and TTransport structures, very similar to the way it's done in C++. Now I'm stuck on how to create the actual connection to the Cassandra server. It should be a function generated by the Cassandra thrift interface, but I can't seem to find the proper one. Any help would be very much appreciated.
