Description:
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 setting | H5Dopen mapping |
|---|
Global settings |
| No compatibility flag | H5Dopen2 |
| Enable deprecated symbols | H5Dopen2 |
| Disable deprecated symbols | H5Dopen2 |
Emulate Release 1.6 interface | H5Dopen1 |
Function-level macros |
H5Dopen_vers = 2 | H5Dopen2 |
H5Dopen_vers = 1 | H5Dopen1 |
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.
Example:
History:
| Release | Change |
|---|
| 1.8.0 | The function H5Dopen renamed to H5Dopen1 and deprecated in this release.
The macro H5Dopen and the function H5Dopen2 introduced in this release. |
