> the function to get the datadds? and print it on the screeen

You can get the dds in a browser by just appending ".dds" to the 
OPeNDAP URL.  The netCDF library doesn't provide a function for
that kind of low-level access.  NetCDF functions give you access
to the data as native data types in a program.

Another way to see what's in the URL is to use the ncdump utility,
providing a URL instead of a file names, as in:

  ncdump 
'http://thredds.ucar.edu/thredds/dodsC/fmrc/NCEP/GFS/Hawaii_160km/NCEP-GFS-Hawaii_160km_best.ncd?Total_precipitation'
 | head 100

That will show the dimensions, variables, and attributes, as well as data, e.g.:

netcdf NCEP-GFS-Hawaii_160km_best {
dimensions:
        time1 = 62 ;
        x = 93 ;
