Name: H5Fget_info
Signature:
herr_t H5Fget_info( hid_t obj_id, H5F_info_t *file_info )

herr_t H5Fget_info( hid_t obj_id, H5F_info_t *file_info )

Purpose:
Opens the HDF5 object referenced.

Description:
H5Fget_info is a macro that is mapped to either H5Fget_info1 or H5Fget_info2, depending on the needs of the application.

Similarly, the macro for the H5F_info_t struct is mapped to either H5F_info1_t or H5F_info2_t.

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, H5Fget_info is mapped to the most recent version of the function, currently H5Fget_info2. If the library and/or application is compiled for Release 1.8 emulation, H5Fget_info will be mapped to H5Fget_info1. Since there was no H5Fget_info function in Release 1.6, if the library and/or application is compiled for Release 1.6 emulation, H5Fget_info will be mapped to the most recent version of the function, currently H5Fget_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:
