Hi,
I tried to use the H5Pset_obj_track_times functionality but when I want to get
back the information, only change time (ctime) is filled in the H5O_info_t. The
modification date is never set.
Does anyone have an experience on this feature?
I'm using HDF5 1.8.7.
Here is one example (C++) of my trial:
H5::H5File file("c:\\TEMP\\test.hdf5");
hsize_t dim = 2;
H5::DataSpace dataspace(1, &dim);
H5::DSetCreatPropList plist;
H5Pset_obj_track_times(plist.getId(), true);
H5::DataSet dataset1 = file.createDataSet("ds1", H5::PredType::NATIVE_CHAR,
dataspace, plist );
H5O_info_t object_info;
H5Oget_info(dataset1.getId(), &object_info); // btime, atime and mtime = 0
int new_value[] = {99, -13};
dataset1.write(new_value, H5::PredType::NATIVE_INT);
H5O_info_t object_info2;
H5Oget_info(dataset1.getId(), &object_info2);
dataset1.createAttribute("a1", H5::PredType::NATIVE_INT, dataspace);
H5O_info_t object_info4;
H5Oget_info(dataset1.getId(), &object_info4); // only ctime updated,
others = 0
Thanks,
Laurent
