H5Dopen
is a macro that is mapped to either
H5Dopen1
or
H5Dopen2
,
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,
H5Dopen
is mapped to the most recent version of
the function, currently
H5Dopen2
.
If the library and/or application is compiled for Release 1.6
emulation, H5Dopen
will be mapped to
H5Dopen1
.
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
H5Dclose
when the dataset is no longer needed
so that resource leaks will not develop.
