Hi all,

How do I get the number of groups, datasets in a existed HDF5 file? I do
not find a subroutine to do this job.

Thanks for help!

In the same way that you cannot know the number of directories and files in a
filesystem without walking every directory and build grand totals, you cannot
do that in HDF5 either. You will need to walk every group and compute your
desired grand totals.

Thanks for relying. I hope HDF5 can provide more comvenient API for doing these querying jobs in Fortran 90, such as getting the number of groups in some spercific level, just like the operation in Linux "ls | wc -l". : )
