Hello, I'm having trouble copying an object to an exterally-linked hdf5 file.I
can copy an object within the same file using H5Ocopy(file_id, "/G4", file_id,
"/G1/G4", H5P_DEFAULT, H5P_DEFAULT)I can create external links using
H5Lcreate_external("file2.h5", "G2", file_id, "G2", H5P_DEFAULT, H5P_DEFAULT)I
can even create a group in the externally-linked file using H5Gcreate(file_id,
"/G2/G3", H5P_DEFAULT, H5P_DEFAULT, H5P_DEFAULT)But I cannot copy to the
externally-linked file, as H5Ocopy(file_id, "/G4", file_id, "/G2/G3/G4",
H5P_DEFAULT, H5P_DEFAULT) gives me an error. I'm wondering what I'm doing
wrong? Or is my version of hdf5 simply out of date?
(Sample code attached) Chris.
