Hi Vlad, This PyTables page shows the output of a Pytables file (tutorial1.h5) using h5ls: http://www.pytables.org/usersguide/tutorials.html
It is a compound datatype. On the Examples by API page are C examples: https://support.hdfgroup.org/HDF5/examples/api-c.html Under “Datatypes” is an example to “Read / Write Compound Datatypes (Dataset)”: h5ex_t_cmpd.c Also, the High Level Table (H5TB) APIs allow you how to create and modify simple tables (compound datatypes) in HDF5. There is a tutorial here, in case that might help: https://support.hdfgroup.org/HDF5/Tutor/h5table.html -Barbara From: Hdf-forum [mailto:hdf-forum-boun...@lists.hdfgroup.org] On Behalf Of Vlad Danilov Sent: Tuesday, November 21, 2017 8:58 AM To: HDF Users Discussion List Subject: Re: [Hdf-forum] ***SPAM*** H5T_ARRAY The problem solved, i just had to install 'blosc' filter and put it into default dir /usr/local/hdf5/lib/plugin But i have a question, maybe it's a bit offtopic, but still - does somebody knows how to read PyTables in hdf5 format using C API? thank You Понедельник, 20 ноября 2017, 15:30 +01:00 от Rafal Lichwala <syri...@man.poznan.pl<mailto:syri...@man.poznan.pl>>: Hello Vlad, Please send me example HDF5 file and your current C code which you are trying to use to read that file and I will try to find a solution.
