Consider the case where you know the names of not only the netCDF datasets, but also the names of their dimensions, variables, and attributes. The order of typical C calls to read data from those variables in a netCDF dataset is (with arguments and error handling not shown):

     nc_open                /* open existing netCDF dataset */
          ...
        nc_inq_dimid        /* get dimension IDs */
          ...
        nc_inq_varid        /* get variable IDs */
          ...
        nc_get_att          /* get attribute values */
          ...
        nc_get_var          /* get values of variables */
          ...
     nc_close               /* close netCDF dataset */
