H5D_OPEN is a macro that is mapped to either H5D_OPEN1 or H5D_OPEN2, depending on the needs of the application.

Such macros are provided to facilitate application compatibility. Their 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, H5D_OPEN is mapped to the most recent version of the function, currently H5D_OPEN2. If the library and/or application is compiled for Release 1.6 emulation, H5D_OPEN will be mapped to H5D_OPEN1. 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 settingH5Dopen mapping

Global settings
No compatibility flagH5Dopen2 
Enable deprecated symbolsH5Dopen2 
Disable deprecated symbolsH5Dopen2 
Emulate Release 1.6 interface    H5Dopen1 

Function-level macros
H5Dopen_vers = 2H5Dopen2
H5Dopen_vers = 1H5Dopen1

A dataset opened with this macro should be closed with H5D_CLOSE when the dataset is no longer needed so that resource leaks will not develop.


Coming Soon!
