Here's the response from Lynton Appel:

... The following will loop through a a set of files. At each pass
through the loop, the destructor functions for NcDim and NcFile are
called; in particular the NcFile destructor will issue a call to
nc_close. So, in my view the API is working correctly.

#include <string>
#include <iostream>
#include <netcdf>

using namespace std;
using namespace netCDF;


int main(int argc, char* argv[])
{
  char* fileName[] = {"efitOut.nc","efitOut2.nc"};
 int i;
  for(i=0;i<2;i++)
    {
      NcFile ncFile(fileName[i],NcFile::replace);
      NcDim timeDim(ncFile.addDim("time",2));
    }
  return 1;
}
