H5Pget_filter
is a macro that is mapped to either
H5Pget_filter1
or
H5Pget_filter2
,
depending on the needs of the application.
Such macros are provided to facilitate application compatibility. For example:
H5Pget_filter
macro
will be mapped to H5Pget_filter1
and
will use the H5Pget_filter1
syntax
(first signature above)
if an application is coded for HDF5 Release 1.6.x.
H5Pget_filter
macro
mapped to H5Pget_filter2
and
will use the H5Pget_filter2
syntax
(second signature above)
if an application is coded for HDF5 Release 1.8.x.
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,
H5Pget_filter
is mapped to the most recent version of
the function, currently
H5Pget_filter2
.
If the library and/or application is compiled for Release 1.6
emulation, H5Pget_filter
will be mapped to
H5Pget_filter1
.
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 setting | H5Pget_filter mapping |
---|---|
Global settings |
|
No compatibility flag | H5Pget_filter2 |
Enable deprecated symbols | H5Pget_filter2 |
Disable deprecated symbols | H5Pget_filter2 |
Emulate Release 1.6 interface |
H5Pget_filter1 |
Function-level macros |
|
H5Pget_filter_vers = 2 |
H5Pget_filter2 |
H5Pget_filter_vers = 1 |
H5Pget_filter1 |
H5Pget_filter
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
H5Pget_filter1
.
Signature [2] above was introduced with HDF5 Release 1.8.0
and is the recommended and default interface.
It is directly callable as
H5Pget_filter2
.
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.
