H5Topen
is a macro that is mapped to either
H5Topen1
or
H5Topen2
,
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,
H5Topen
is mapped to the most recent version of
the function, currently
H5Topen2
.
If the library and/or application is compiled for Release 1.6
emulation, H5Topen
will be mapped to
H5Topen1
.
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 | H5Topen mapping |
---|---|
Global settings |
|
No compatibility flag | H5Topen2 |
Enable deprecated symbols | H5Topen2 |
Disable deprecated symbols | H5Topen2 |
Emulate Release 1.6 interface |
H5Topen1 |
Function-level macros |
|
H5Topen_vers = 2 |
H5Topen2 |
H5Topen_vers = 1 |
H5Topen1 |
The datatype identifier returned by this macro can be
released with H5Tclose
when the identifier is
no longer needed so that resource leaks will not develop.
