existence of group

Hdf-forum archives

Hi!

I am using the fortran90 interface to hdf5 1.8 patch 1.

I am unable to find a function that lets me know whether a group exists already. It is clearly not allowed to create an already existing group, so I need to check this with an if (...) statement. Does such a function exist?

Thanks in advance,
Paul.

Paul,

I think the function |H5Lexists |does the job :
http://www.hdfgroup.org/HDF5/doc/RM/RM_H5L.html#Link-Exists

I use it in one of my projects :
http://code.google.com/p/amelet-hdf/source/browse/amelethdf-fortran/trunk/src/amelethdf/hdfpath.f90#36

Regards,

Cyril.

Merci beaucoup Cyril!

I suppose I did not understand the syntax, I was not familiar with the 'link' concept before. I suppose a 'link' is just about anything, like a dataset, a group, or similar? Anyway, thanks again!

Cheers,
Paul.
