hi,
i had run gdalinfo on .nc file. it doesnt have subdatsets. it is rainfall
data. it has 122 bands. how can i get geoextents of this file. and how do i
extract each band from it if i want display band according to the time? how
can i access those variables? i am writing this in C so i want to
It looks like you need to read http://gdal.org/gdal_tutorial.html

and make sure you'r using gdal 1.10.. the netcdf driver is more functional

As Even suggests you should read the tutorial first, most questions will be
answered there.
As for Band extraction, you need to look at the metadata, which you can
inspect with gdalinfo
you should look for metadata like
NETCDF_DIM_time_DEF
NETCDF_DIM_time_VALUES
and band metadata like
the gdal api tutorial will give you pointers on how to access dataset and
band-level metadata

From the GetRasterCount() i can find the number of bands and using vrt i am
creating a file for every band. in order to to show them according to the
NETCDF_DIM_time_VALUES how can i do that?

loop for each raster as explained in the tutorial, and get the specific
metadataitem like this
const char* md = GDALGetMetadataItem(hBand, NETCDF_DIM_time_VALUE, )
md will contain the value of NETCDF_DIM_time_VALUE for that band
