Doxygen Generated Reference Manual
The new HDF5 C-API documentation based on Doxygen is available at
Note that the Fortran-API is NOT included in this release, and will be included in a future release. Online versions can be found at these URLs:
This documentation is WORK-IN-PROGRESS. That’s why all existing documentation will remain accessible for the foreseeable future.
Since this portion of the HDF5 documentation is now part of the source code, it gets the same treatment as code. In other words, issues, inaccuracies, corrections should be reported as issues in GitHub (https://github.com/HDFGroup/hdf5/issues), and pull requests will be reviewed and accepted as any other code changes.
Tested Platforms and Configuration Features
NOTE: HDF5-1.12 requires MPI 3.
See the Supported Platforms section in the Release Notes for details.
