Fortran90 Interface: h5pinsert_f

Signature:
  SUBROUTINE h5pinsert_f
    INTEGER(HID_T)  , INTENT(IN)  :: plist
    CHARACTER(LEN=*), INTENT(IN)  :: name

Description:

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:

Compatibility settingH5Pinsert mapping

Global settings
No compatibility flagH5P_INSERT2 
Enable deprecated symbolsH5P_INSERT2 
Disable deprecated symbolsH5P_INSERT2 
Emulate Release 1.6 interfaceH5P_INSERT1 

Function-level macros
H5Pinsert_vers = 2    H5P_INSERT2
H5Pinsert_vers = 1H5P_INSERT1

For more information on macro use and mappings, see the “API Compatibility Macros in HDF5” document.

 

Interface history:   Signature [1] 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 [2] 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.

Programming Note for C++ Developers Using C Functions:

If a C routine that takes a function pointer as an argument is called from within C++ code, the C routine should be returned from normally.

Examples of this kind of routine include callbacks such as H5P_SET_ELINK_CB and H5P_SET_TYPE_CONV_CB and functions such as H5T_CONVERT and H5E_WALK2.

Exiting the routine in its normal fashion allows the HDF5 C library to clean up its work properly. In other words, if the C++ application jumps out of the routine back to the C++ “catch” statement, the library is not given the opportunity to close any temporary data structures that were set up when the routine was called. The C++ application should save some state as the routine is started so that any problem that occurs might be diagnosed.
