/**
 * \ingroup H5O
 * \def H5Ovisit()
 *
 * #H5Ovisit is a macro that is mapped to one of the following:
 * \li H5Ovisit3()
 * \li H5Ovisit1()
 *
 * \details 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.
 *
 *          In HDF5 versions 1.12 and after, \ref H5Ovisit() is mapped to 
 *          \ref H5Ovisit3().  In version 1.10, \ref H5Ovisit() is identical 
 *          to \ref H5Ovisit1().
 *
 *          Specific compile-time compatibility flags and the resulting
 *          mappings are as follows:
