H5P_INSERT is a macro that is mapped to either H5P_INSERT1 or H5P_INSERT2, depending on the needs of the application.
Such macros are provided to facilitate application compatibility. For example:
- The H5P_INSERT macro will be mapped to H5P_INSERT1 and will use the H5P_INSERT1 syntax (first signature above) if an application is coded for HDF5 Release 1.6.x.
- The H5P_INSERT macro mapped to H5P_INSERT2 and will use the H5P_INSERT2 syntax (second signature above) if an application is coded for HDF5 Release 1.8.x.
When both the HDF5 library and the application are built and installed with no specific compatibility flags, H5P_INSERT is mapped to the most recent version of the function, currently H5P_INSERT2. If the library and/or application is compiled for Release 1.6 emulation, H5P_INSERT will be mapped to H5P_INSERT1. 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|
H5Pinsert_vers = 2
H5Pinsert_vers = 1
For more information on macro use and mappings, see the “API API Compatibility Macros in HDF5” HDF5 document.
Interface history: Signature  above is the original H5P_INSERT interface and the only interface available prior to HDF5 Release 1.8.0. This signature and the corresponding function are now deprecated but will remain directly callable as H5P_INSERT1.
Signature  above was introduced with HDF5 Release 1.8.0 and is the recommended and default interface. It is directly callable as H5P_INSERT2.
See “API Compatibility Macros in HDF5” for circumstances under which either of these functions might not be available in an installed instance of the HDF5 library.
