H5G_OPEN is a macro that is mapped to either H5G_OPEN1 or H5G_OPEN2, depending on the needs of the application.
Such macros are provided to facilitate application compatibility. For more information on macro use and mappings, see the API Compatibility Macros in HDF5 document.
When both the HDF5 library and the application are built and installed with no specific compatibility flags, H5G_OPEN is mapped to the most recent version of the function, currently H5G_OPEN2. If the library and/or application is compiled for Release 1.6 emulation, H5G_OPEN will be mapped to H5G_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:
|No compatibility flag|
|Enable deprecated symbols|
|Disable deprecated symbols|
|Emulate Release 1.6 interface|
H5Gopen_vers = 2
H5Gopen_vers = 1
A group created with this macro should be closed with H5G_CLOSE when the group is no longer needed so that resource leaks will not develop.
|1.8.0||The function |
H5Gopen renamed to
H5Gopen1 and deprecated in this release.
H5Gopen and the function
H5Gopen2 introduced in this release.
