Keep the following in mind when looking at the example programs included in this tutorial:
APIs vary with different languages
- C routines begin with the prefix “H5*” where * is a single letter indicating the object on which the operation is to be performed:
File Interface:H5Fopen
Dataset Interface:H5Dopen - FORTRAN routines begin with “h5*” and end with “_f”:
File Interface:h5fopen_f
Dataset Interface:h5dopen_f - APIS for languages like C++, Java, and Python use methods associated with specific objects.
HDF5 library has its own defined types
For portability, the HDF5 library has its own defined types. Some common types that you will see in the example code are:
hid_t is used for object handles
hsize_t is used for dimensions
herr_t is used for many return values
Language specific files must be included in applications
C: Add #include hdf5.h
FORTRAN: Add USE HDF5 and call h5open_f and h5close_f to initialize and close the HDF5 FORTRAN interface
Python: Add import h5py / import numpy
