| Dimension #n Scaled Offset | This field is the scaled offset of the chunk within the dataset. n is the number of dimensions for the dataset. The first scaled offset stored in the list is for the slowest changing dimension, and the last scaled offset stored is for the fastest changing dimension. Scaled offset is calculated by dividing the chunk dimension sizes into the chunk offsets. |

The HDF5 error API (Error Handling (H5E)) manages the behavior of the error stack in the HDF5 library. This API is omitted from the JHI5. Errors are converted into Java exceptions. This is totally different from the C interface, but is very natural for Java programming.
The exceptions of the JHI5 are organized as sub-classes of the class Errors and Exceptions HDF5Exception. There are two subclasses of HDF5Exception, HDF5 Library Errors and Exceptions HDF5LibraryException and Java Wrapper Errors and Exceptions HDF5JavaException. The sub-classes of the former represent errors from the HDF5 C library, while sub-classes of the latter represent errors in the JHI5 wrapper and support code.
The super-class HDF5LibraryException implements the method 'printStackTrace()', which prints out the HDF5 error stack, as described in the HDF5 C API H5Eprint(). This may be used by Java exception handlers to print out the HDF5 error stack.

HISTORY files
The HISTORY files contain the history of this branch of HDF5. They fall into three categories.

HISTORY-[VERSION 1]-[VERSION 2].txt
These files are created when we release a new major version and include all the changes that were made to the develop branch while creating a major release.

HISTORY-[VERSION].txt
This file contains the changes that were made to a maintenance branch since it split off from develop. It will also be found in the develop branch when experimental releases have been created.
-

CHANGELOG.md (formerly RELEASE.txt)
This is the changelog for the current version of the library.
For a MAJOR release (or in develop) this files lists all the changes since the last major version. For a MINOR release (or in a maintenance branch), this file lists all the changes since the last release in the maintenance branch.

- The file in
hdf5_1_14 includes all the changes since the last minor HDF5 1.14 release
Note that we make no effort to bring maintenance branch HISTORY files back to develop. If you want to compare, say, 1.10.4 with 1.12.3, you'd have to get the history files from those releases and compare them by hand.

Detailed Description
This directory contains several test applications that exercise HDF5's public API and serve as regression tests for HDF5 VOL Connectors.
-

Build Process and options
These HDF5 API tests are enabled by default, but can be disabled by passing the -DHDF5_TEST_API=OFF option to CMake. The following build options are available to influence how the API tests get built:
-
+
CMake
To set an option, it should be prepended with -D when passed to the cmake command. For example,
cmake -DHDF5_TEST_API=OFF ..
HDF5_TEST_API (Default: ON) - Determines whether the API tests will be built.
@@ -153,10 +153,10 @@ CMake
HDF5_TEST_API_ENABLE_ASYNC (Default: OFF) - Determines whether tests for HDF5's asynchronous I/O capabilities should be enabled. Note that the "native" HDF5 VOL connector doesn't support this functionality, so these tests are directed towards VOL connectors that do.
HDF5_TEST_ENABLE_DRIVER (Default: OFF) - Determines whether the API test driver program should be built. This driver program is useful when a VOL connector relies upon a server executable (as well as possible additional executables) in order to function. The driver program can be supplied with a server executable and server/client arguments to use when running the API tests.
HDF5_TEST_API_SERVER (Default: empty string) - If HDF5_TEST_ENABLE_DRIVER is set to ON, this option should be edited to point to the server executable that the driver program should attempt to launch before running the API tests.

Autotools
Currently unsupported

+
Usage
These API tests currently only support usage with the native HDF5 VOL connector and HDF5 VOL connectors that can be loaded dynamically as a plugin. For information on how to build a VOL connector in this manner, refer to section 2.3 of the HDF5 VOL Connector Author Guide.
If an HDF5 VOL connector has been built alongside the library, these API tests can be used for testing that VOL connector at the same time that HDF5 is test. For more information on how to build a VOL connector alongside the HDF5 library, refer to Building and testing HDF5 VOL connectors with CMake FetchContent.

The test-pc.sh script can test the examples with the h5*cc pkg-config wrappers with: cd <path to examples> export HDF5_HOME="hdf5 installation root"; sh ./test-pc.sh <path to examples> <path to build dir> . Notice that period (.) at the end of the command is important, it tells the script to use the current directory as the source directory.

H5Pencode2() encodes the property list plist_id into the binary buffer buf, according to the file format setting specified by the file access property list fapl_id.
If the required buffer size is unknown, buf can be passed in as NULL and the function will set the required buffer size in nalloc. The buffer can then be created and the property list encoded with a subsequent H5Pencode2() call.
If the buffer passed in is not big enough to hold the encoded properties, the H5Pencode2() call can be expected to fail with a segmentation fault.
-The file access property list fapl_id is used to control the encoding via the libver_bounds property (see H5Pset_libver_bounds()). If the libver_bounds property is missing, H5Pencode2() proceeds as if the libver_bounds property were set to (H5F_LIBVER_V18, H5F_LIBVER_LATEST). (Functionally, H5Pencode1() is identical to H5Pencode2() with libver_bounds set to (H5F_LIBVER_V18, H5F_LIBVER_LATEST).) Properties that do not have encode callbacks will be skipped. There is currently no mechanism to register an encode callback for a user-defined property, so user-defined properties cannot currently be encoded.

If the libver_bounds property is missing, H5Pencode2() proceeds as if the libver_bounds property were set to (H5F_LIBVER_EARLIEST, H5F_LIBVER_LATEST).

There is currently no mechanism to register an encode callback for a user-defined property, so user-defined properties cannot currently be encoded.
Some properties cannot be encoded, particularly properties that are reliant on local context.
Motivation: This function was introduced in HDF5-1.12 as part of the H5Sencode format change to enable 64-bit selection encodings and a dataspace selection that is tied to a file.

For a first contact with HDF5, the best place is to have a look at the getting started page that shows you how to write and compile your first program with HDF5.
The main documentation is organized by documentation flavor. Most technical documentation consists to varying degrees of information related to tasks, concepts, or reference material. As its title suggests, the Reference Manual is 100% reference material, while the Cookbook is focused on tasks. The different guide-type documents cover a mix of tasks, concepts, and reference, to help a specific audience succeed.

Linux/macOS:
Windows (PowerShell):
Windows (CMD):
Note: The test scripts automatically add ${HDF5_HOME}/lib (Unix) or HDF5_HOME%\bin (Windows) to the library path.
Note: This is an advanced option. Prefer using HDF5_HOME (Option 3) instead.
After installing HDF5, verify the libraries are accessible:

Reason: Native libraries are platform-specific and typically hundreds of MB. Maven artifacts should be small (~2-5 MB) and platform-independent where possible. The JNI/FFM bindings provide the Java interface, but you must install the native HDF5 libraries separately.

CMake produces the following set of folders; bin, include, lib and share. The LICENSE and CHANGELOG.md file are placed in the share folder.
+CMake produces the following set of folders; bin, include, lib and share. The LICENSE and RELEASE.txt file are placed in the share folder.
The bin folder contains the tools and the build scripts. Additionally, CMake creates dynamic versions of the tools with the suffix "-shared".
The include folder holds the header files and the fortran mod files. CMake places the fortran mod files into separate shared and static subfolders, however the use of HDF5_INSTALL_MOD_FORTRAN places one set of mod files into the include folder. Because CMake produces a tools library, the header files for tools will appear in the include folder.
The lib folder contains the library files, and CMake adds the pkgconfig subfolder with the hdf5*.pc files used by the bin/build scripts created by the CMake build. CMake separates the C interface code from the fortran code by creating C-stub libraries for each Fortran library. In addition, only CMake installs the tools library. The names of the szip libraries are different between the build systems.
CMake builds include a number of CMake specific files for support of CMake's find_package and support for the HDF5 Examples CMake project.

-A common historical use case was compiling for Intel Knights Landing (KNL) nodes on Cray XC40 systems, such as the retired Mutrino and Cori machines. These supercomputers had login nodes with a standard CPU architecture (e.g., Haswell) but used the different KNL architecture for their compute nodes.
To build software for KNL, a "module swapping" technique was required. The build process involved:

While cross-compilation is less common on many modern, homogeneous HPC clusters, it is still a necessary technique for advanced architectures, such as systems with different processor types or accelerators (e.g., GPUs).
If you need assistance with cross-compiling for a current HPC system, please contact the facility administrators or The HDF Group (Section 1.3).

Here are sample MPI-IO C and Fortran programs to test your MPI compiler and parallel file system before building HDF5. The programs assume they run in a parallel file system (create test files in current directory). For more examples, please refer to the following directories: HDF5Examples/C/H5PAR and HDF5Examples/FORTRAN/H5PAR

Release a new version of HDF software, which corrects defects, adds functionality, improves maintainability, and/or ports it to new operational environments.
-At regularly scheduled intervals throughout each year, The HDF Group releases a new version of each of its maintained/core software products and corresponding documentation set. This is referred to as a maintenance release. The main purpose of a maintenance release is to address defects reported against previous releases of the software, to port the software to new operating environments, and to improve maintainability by way of refactoring code and improving documentation. A maintenance release may also include new functionality in any of the product's components.
Depending on the software being released, there may be specific guidelines that are followed or steps that are performed in addition to the 'standard' maintenance release procedure - in such a case, product-specific tabs are provided within the page to view information specific to only that product.
-Twice each year, The HDF Group releases a new version of the HDF5 C, C++, and Fortran libraries and command line utilities and associated documentation set. This is referred to as a maintenance release of HDF5. The main purpose of a maintenance release is to address defects reported against previous releases of the software, to port HDF5 to new operating environments, and to improve maintainability by way of refactoring code and improving documentation. A maintenance release may also include new functionality in the C, C++, and Fortran libraries and/or command line utilities if requested and/or funded by the user community and/or The HDF Group's customers. The new features included in a maintenance release expand the feature set only and do not change the HDF5 file format, with the exception of addressing critical defects that corrupt data.
Maintenance releases are always backward compatible with regards to the HDF5 file format, meaning that:

-git status --ignored;, then running genparser, then repeating git status --ignored;. If there are modified files from either git status command, they should be committed (or deleted if there are backup files or an autom4te.cache directory), and at least minimal testing should be done to see that the software is still good with the changes.

-The new HDF5 documentation based on Doxygen is available here.
-This documentation is WORK-IN-PROGRESS.
-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, and pull requests will be reviewed and accepted as any other code changes.
-This section highlights some changes that might affect migrating to HDF5.20, please refer to the Software Changes from Release to Release in HDF5 2.0 or the Change log for detail.
-H5Dread_chunk()H5Tdecode()H5Iregister_type()aws-c-s3 library in order to be built. See the Change log for a complete description on this feature. --lformat and its XML option is deprecated.h52gif and gif2h5 have been removed. We may move them to a separate repository in the future. See Change log for an explanation.This section includes the new features introduced in the HDF5 2.0 series:
-float _Complex, double _Complex and long double _Complex (with MSVC, _Fcomplex, _Dcomplex and _Lcomplex) types has been added for platforms/compilers that support them. These types have been implemented with a new datatype class, H5T_COMPLEX. Note that any datatypes of class H5T_COMPLEX will not be readable with previous versions of HDF5. If a file is accessed with a library version bounds "high" setting less than H5F_LIBVER_V200, an error will occur if the application tries to create an object with a complex number datatype. If compatibility with previous versions of HDF5 is desired, applications should instead consider adopting one of the existing conventions.--endpoint-url, which allows the user to set an alternate endpoint URL other than the standard "protocol://service-code.region-code.amazonaws.com". If --endpoint-url is not specified, the ROS3 VFD will first check the AWS_ENDPOINT_URL_S3 and AWS_ENDPOINT_URL environment variables for an alternate endpoint URL before using a default one, with the region-code being supplied by the FAPL or standard AWS locations/environment variables. h5dump, h5ls, h5stath5dump, h5ls, h5stat.H5Pset_cache() or H5Pset_chunk_cache(). This value was chosen because it is a prime number close to 8K.Software Changes from Release to Release in HDF5 2.0

This page provides information on the changes that a maintenance developer needs to be aware of between successive releases of HDF5, such as:
See API Compatibility Macros for details on using HDF5 version 2.0 with previous releases.
-The Change log (a.k.a. the RELEASE.txt prior to release 2.0) also lists changes made to the library, but these notes tend to be more at a more detail-oriented level. It include new features, bugs fixed, supported configuration features, platforms on which the library has been tested, and known problems. The change log files are listed in each release section and can be found at the top level of the HDF5 source code tree in the release_docs directory.
-HDF5 version 2.0 provides a number of new C APIs and other user-visible changes in behavior in the transition from HDF5 Release 1.14.6 to Release 2.0. Some of those require the use of the API Compatibility Macros for the main library. In addition, some APIs have been removed or have had their signature change.
-#hbool_t has been removed from public API calls #hbool_t type was introduced before the library supported C99's Boolean type. Originally typedef'd to an integer, it has been typedef'd to C99's bool for many years. Prior to HDF5 2.0, it had been purged from the library code and only remained in public API signatures. In HDF5 2.0, it has also been removed from public API signatures. #hbool_t typedef remains in H5public.h so existing code does not need to be updated.H5Pset_fapl_ros3() now has the side effect of setting the page buffer size in the FAPL to 64 MiB if it was not previously set. This will only have an effect if the file uses paged allocation. Also added the #H5F_PAGE_BUFFER_SIZE_DEFAULT to allow the user to unset the page buffer size in an FAPL so it can be similarly overridden.nalloc, has been added to H5Dread_chunk(). This parameter contains a pointer to a variable that holds the size of the buffer buf. If *nalloc is not large enough to hold the entire chunk being read, no data is read. On exit, the value of this variable is set to the buffer size needed to read the chunk. The old signature has been renamed to H5Dread_chunk1() and is considered deprecated: H5Dread_chunk2(). All code should be updated to use this version: H5Dread_chunk() will map to the new signature unless the library is explicitly configured to use an older version of the API.buf_size, has been added to H5Tdecode() to prevent walking off the end of the buffer. The old signature has been renamed to H5Tdecode1() and is considered deprecated: H5Tdecode2(). All code should be updated to use this version: H5Tdecode() will map to the new signature unless the library is explicitly configured to use an older version of the API.H5Iregister_type1() and is considered deprecated: H5Iregister_type() will map to the new signature unless the library is explicitly configured to use an older version of the API.List of new public APIs/Macros
