H5Acreate is a macro that is mapped to either
H5Acreate1 or
H5Acreate2,
depending on the needs of the application.
Such macros are provided to facilitate application compatibility. For example:
H5Acreate macro
will be mapped to H5Acreate1 and
will use the H5Acreate1 syntax
(first signature above)
if an application is coded for HDF5 Release 1.6.x.
H5Acreate macro
mapped to H5Acreate2 and
will use the H5Acreate2 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,
H5Acreate is mapped to the most recent version of
the function, currently
H5Acreate2.
If the library and/or application is compiled for Release 1.6
emulation, H5Acreate will be mapped to
H5Acreate1.
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 | H5Acreate mapping |
|---|---|
Global settings |
|
| No compatibility flag | H5Acreate2 |
| Enable deprecated symbols | H5Acreate2 |
| Disable deprecated symbols | H5Acreate2 |
Emulate Release 1.6 interface |
H5Acreate1 |
Function-level macros |
|
H5Acreate_vers = 2 |
H5Acreate2 |
H5Acreate_vers = 1 |
H5Acreate1 |
H5Acreate 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
H5Acreate1.
Signature [2] above was introduced with HDF5 Release 1.8.0
and is the recommended and default interface.
It is directly callable as
H5Acreate2.
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.
