Name: H5Ewalk
Signature:
herr_t H5Ewalk( H5E_direction_t direction, H5E_walk_t func, void * client_data )

herr_t H5Ewalk( hid_t estack_id, H5E_direction_t direction, H5E_walk_t func, void * client_data )
Purpose:
Walks an error stack, calling a specified function.
Description:
H5Ewalk is a macro that is mapped to either H5Ewalk1 or H5Ewalk2, depending on the needs of the application.

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, H5Ewalk is mapped to the most recent version of the function, currently H5Ewalk2. If the library and/or application is compiled for Release 1.6 emulation, H5Ewalk will be mapped to H5Ewalk1. 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 H5Ewalk mapping

Global settings
No compatibility flag H5Ewalk2 
Enable deprecated symbols H5Ewalk2 
Disable deprecated symbols H5Ewalk2 
Emulate Release 1.6 interface     H5Ewalk1 

Function-level macros
H5Ewalk_vers = 2 H5Ewalk2
H5Ewalk_vers = 1 H5Ewalk1

Fortran90 Interface:
None.
