! NAME
! H5O_PROVISIONAL
!
! PURPOSE
! This file contains Fortran 90 and Fortran 2003 interfaces for H5O functions.
! It contains the same functions as H5Off_DEPRECIATE.f90 but includes the
! Fortran 2003 functions and the interface listings. This file will be compiled
! instead of H5Off_DEPRECIATE.f90 if Fortran 2003 functions are enabled.

! If you add a new H5P function you must add the function name to the
! Windows dll file 'hdf5_fortrandll.def' in the fortran/src directory.
! This is needed for Windows based operating systems.

!
! PURPOSE
! Recursively visits all objects starting from a specified object.
!
! INPUTS
! group_id - Identifier of the group at which the recursive iteration begins
! index_type - Type of index; valid values include:
! H5_INDEX_NAME_F
! H5_INDEX_CRT_ORDER_F
! order - Order in which index is traversed; valid values include:
! H5_ITER_DEC_F

! H5_ITER_NATIVE_F
! op - Callback function passing data regarding the group to the calling application
! op_data - User-defined pointer to data required by the application for its processing of the group
!
! OUTPUTS
! idx - returns the return value of the first operator that returns a positive value, or
! zero if all members were processed with no operator returning non-zero.
