One thing: you mention you intend to use the signature
NcBool put(const ....* vals, const long* counts)
but when you call
data->put(&dataOut[0], *dim);
(note the "*dim" which dereferences to a long, rather than long *)
it'll call a different member function, namely
NcBool put( const int* vals, long c0=0, long c1=0, ... )
Instead you'd probably want
data->put(&dataOut[0], dim);
Right?
