hdf5/c++/test/dsets.cpp
Binh-Minh Ribler f6d9d1fdc8 [svn-r26695] Purpose: Fixed HDFFV-7947 (cont.)
Description:
    - Put back the UNUSED parameters in dsets test because the change to remove
      the warning last time caused failure in setting filter, in turn, caused
      failure in the test with such obscure/unrelated errors!
    - Added incRefCount() to other constructors that missed from last time.
Platforms tested:
    Linux/64 (platypus)
    Linux/32 2.6 (jam)
    SunOS 5.11 (emu)

* Modifications:
* Nov 12, 01:
* - moved h5_cleanup to outside of try block because
* dataset.h5 cannot be removed until "file" is out of
* scope and dataset.h5 is closed.
* Feb 20, 05:
* - cleanup_dsets took care of the cleanup now.
