Calls a user’s function for each attribute on an object
H5A_ITERATE is a macro that is mapped to either H5A_ITERATE1 or H5A_ITERATE2, depending on the needs of the application.
Such macros are provided to facilitate application compatibility. For example:
- The H5A_ITERATE macro will be mapped to H5A_ITERATE1 and will use the H5A_ITERATE1 syntax (first signature above) if an application is coded for HDF5 Release 1.6.x.
- The H5A_ITERATE macro mapped to H5A_ITERATE2 and will use the H5A_ITERATE2 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, H5A_ITERATE is mapped to the most recent version of the function, currently H5A_ITERATE2. If the library and/or application is compiled for Release 1.6 emulation, H5A_ITERATE will be mapped to H5A_ITERATE1. 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:
|No compatibility flag|
|Enable deprecated symbols|
|Disable deprecated symbols|
|Emulate Release 1.6 interface|
H5Aiterate_vers = 2
H5Aiterate_vers = 1
Interface history: Signature  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 H5A_ITERATE1.
Signature  above was introduced with HDF5 Release 1.8.0 and is the recommended and default interface. It is directly callable as H5A_ITERATE2.
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.
