H5F_GET_INFO is a macro that is mapped to either H5F_GET_INFO1 or H5F_GET_INFO2, depending on the needs of the application.
Similarly, the macro for the
H5F_info_t struct is mapped to either
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, H5F_GET_INFO is mapped to the most recent version of the function, currently H5F_GET_INFO2. If the library and/or application is compiled for Release 1.8 emulation, H5F_GET_INFO will be mapped to H5F_GET_INFO1. Since there was no H5F_GET_INFO function in Release 1.6, if the library and/or application is compiled for Release 1.6 emulation, H5F_GET_INFO will be mapped to the most recent version of the function, currently H5F_GET_INFO2. 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|
|Emulate Release 1.8 interface|
