HDF5: API Specification
Reference Manual

The HDF5 library provides several interfaces, each of which provides the tools required to meet specific aspects of the HDF5 data-handling requirements.

A note regarding the prototype FORTRAN90 APIs:
This version of the
HDF5 Reference Manual includes a description of a partial FORTRAN90 prototype API to HDF5. Prototype Fortran subroutines exist in the H5A, H5D, H5F, H5G, H5P, H5S, and H5T interfaces and are described on those pages.

In general, each Fortran subroutine performs exactly the same task as the corresponding C function. The links at the top of each reference manual section go to the C function descriptions, which serve as general descriptions for both the C and Fortran APIs. A button, under Non-C API(s) at the end of the C function description, opens an external browser window displaying the Fortran-specific information. You will probably want to adjust the size and location of this external window so that both browser windows are visible and to facilitate moving easily between them.

See README_Fortran90.html, a copy of the README file in the Fortran prototype source code directory, for more detailed notes regarding the prototype API.
