<h1>HDF5: API Specification<br>Reference Manual</h1>


</center>
The HDF5 library provides several interfaces, each of which provides the 
tools required to meet specific aspects of the HDF5 data-handling requirements.
<p>
See <a href="#F90andCPPlus">below</a> for the FORTRAN90 and C++ APIs.

<h3>The Fortran90 and C++ APIs to HDF5</h3>
</a>

The HDF5 Library distribution now includes FORTRAN90 and C++ APIs.
These APIs are described in the following documents.

<p>
<strong>Fortran90 API</strong>
    <dir>
    <a href="fortran/F90UserNotes.html" target="External">
    <cite>HDF5 FORTRAN90 User's Notes</cite></a>
    contains general information regarding the API.
    Specific information on each API call is found in the 
    <cite>Reference Manual</cite>.
    <p>
    <u>Fortran90 APIs in the <cite>Reference Manual</cite>:</u>
    The current version of the <cite>HDF5 Reference Manual</cite> includes 
    a description of the FORTRAN90 API to HDF5.
    Fortran subroutines exist in the H5A, H5D, H5E, H5F, H5G, H5I, H5P, 
    H5R, H5S, and H5T interfaces and are described on those pages.
    <p>  
    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 
    <strong>Non-C API(s)</strong> 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.
    <p>
    <a href="fortran/F90Flags.html" target="External">
    <cite>HDF5 Fortran90 Flags and Datatypes</cite></a>
    lists the flags employed in the Fortran90 interface and 
    contains a pointer to the HDF5 Fortran90 datatypes.
    </dir>

<strong>C++ API</strong>
    <dir>
    <a href="cpplus/CppUserNotes.pdf" target="External">
    <cite>HDF5 C++ User's Notes</cite></a>
    <p>
    <a href="cpplus/CppInterfaces.html" target="External">
    <cite>HDF5 C++ Interfaces</cite></a>
    <p>
    (Note that the C++ APIs are not yet integrated into the 
    <cite>HDF5 Reference Manual</cite>.)
