HDF5 C API

The HDF5 library provides several interfaces, or APIs. These APIs provide routines for creating, accessing, and manipulating HDF5 files and objects.

The library itself is implemented in C. To facilitate the work of FORTRAN 90, C++ and Java programmers, HDF5 function wrappers have been developed in each of these languages. This tutorial discusses the use of the C functions and the FORTRAN wrappers.

All C routines in the HDF5 library begin with a prefix of the form H5*, where * is one or two uppercase letters indicating the type of object on which the function operates. The FORTRAN wrappers come in the form of subroutines that begin with h5 and end with _f. Java routine names begin with “H5*” and are prefixed with “H5.” as the class. Constants are in the HDF5Constants class and are prefixed with "HDF5Constants.". The APIs are listed below:
