Yilmaz,

I did not see any obvious problem with your code or explanation of why
it might be failing.

Use:

   OGRSpatialReference *poSRS = (OGRSpatialReference *)
         OSRNewSpatialReference(NULL);

You may need to include ogr_srs_api.h.  The OSR functions are
the C version of the ogr_spatialref.h C++ interface and can
be mixed with c++ with a bit of casting.
