Packet Table a few questions...

Dear list users,

I am trying to use the Packet Table (PT) HL api and have a few questions.
1) Is it possible to use PT without zlib or any compression?
4) Is it possible to use Packet Table fixed length without zlib but
with szip instaed?
2) When building the ptcppExmpleFL.cpp I am getting the following
linking error.
1>PTFixedLengthTest.obj : error LNK2001: unresolved external symbol
_H5T_NATIVE_INT_g
is it due to the fact that I configured HDF5lib without zlib?
3) If the cpp api is just a wrapper to the PT c api than why in the
FL_PacketTable constructor
FL_PacketTable(hid_t fileID, char* name, hid_t dtypeID, int chunkSize)
the paramater compression given in the C API create function is missing???

hid_t H5PTcreate_fl( hid_t loc_id, const char * dset_name, hid_t
dtype_id, hsize_t chunk_size, int compression )

Thanks in advance & regards
Eryk

Regarding your #3: compression is default to -1:

FL_PacketTable(hid_t fileID, char* name, hid_t dtypeID, hsize_t chunkSize,
int compression = -1);

Where did you see the constructor prototype without the compression
parameter?

I just read the "HDF5 Packet Table C++ Wrappers" documentation and
only 4 parameters are documented....
http://www.hdfgroup.org/HDF5/doc/HL/RM_H5PT_c++.html

BTW.

The links to the example files from "Introduction to the HDF5 Packet
Table API" http://www.hdfgroup.org/HDF5/doc/HL/H5PT_Intro.html
are all broken, i.e:
www.hdfgroup.org/HDF5/doc/HL/Examples/ptcppExampleVL.cpp

while the files can still be found at the server for example at the location:
www.hdfgroup.org/HDF5/hdf5_hl/doc/Examples/ptcppExampleFL.cpp

it seems that adding /hdf5_hl/ to the links in the document would fix
the broken links.

Good luck!

Hello Eryk,

First, thanks for reporting the broken links! I can't speak to the
rest of the issues you were asking about earlier, but the broken links
to the H5PT examples should now be fixed.

Regards,
