Description:
HTML Wrap
classhdf-rm-section

H5Aiterate is a macro that is mapped to either H5Aiterate1 or H5Aiterate2, depending on the needs of the application.

Such macros are provided to facilitate application compatibility. For example:

  • The H5Aiterate macro will be mapped to H5Aiterate1 and will use the H5Aiterate1 syntax (first signature above) if an application is coded for HDF5 Release 1.6.x.
  • The H5Aiterate macro mapped to H5Aiterate2 and will use the H5Aiterate2 syntax (second signature above) if an application is coded for HDF5 Release 1.8.x.

Macro use and mappings are fully described in “API Compatibility Macros in HDF5”; we urge you to read that document closely.

When both the HDF5 Library and the application are built and installed with no specific compatibility flags, H5Aiterate is mapped to the most recent version of the function, currently H5Aiterate2. If the library and/or application is compiled for Release 1.6 emulation, H5Aiterate will be mapped to H5Aiterate1. Function-specific flags are available to override these settings on a function-by-function basis when the application is compiled.

Specific compile-time compatibility flags and the resulting mappings are as follows:

Compatibility settingH5Aiterate mapping
Global settings 
No compatibility flagH5Aiterate2
Enable deprecated symbolsH5Aiterate2
Disable deprecated symbolsH5Aiterate2
Emulate Release 1.6 interfaceH5Aiterate1
Function-level macros 
H5Aiterate_vers = 2H5Aiterate2
H5Aiterate_vers = 1H5Aiterate1

Interface history:   Signature [1] above is the original H5Aiterate interface and the only interface available prior to HDF5 Release 1.8.0. This signature and the corresponding function are now deprecated but will remain directly callable as H5Aiterate1.

Signature [2] above was introduced with HDF5 Release 1.8.0 and is the recommended and default interface. It is directly callable as H5Aiterate2.

See “API Compatibility Macros in HDF5” for circumstances under which either of these functions might not be available in an installed instance of the HDF5 Library.
