Hi Daniel, fg_p must point to either a H5File or Group object, not CommonFG. I hope that helps.

Hello, I'm doing my first steps with the C++ API, and there's one problem I can't conquer: I'm trying to test if a dataset exists using the following code: try{ std::cout << "Trying to open DS..." << endl; H5::DataSet foo = fg_p->openDataSet(location); } catch(H5::GroupIException e) { std::cout << "GroupIException" << endl; } catch(H5::FileIException e) { std::cout << "FileIException" << endl; } catch (...) { std::cout << "Caught by ..." << endl; return false; } return true; fg_p is a pointer to a CommonFG object, location is a string here. For datasets that exist it works alright, but for a non-existing dataset, only the catch(...) is triggered. What would be the correct exception to catch here? Also is there a way to suppress all the HDF5-DIAG output that I get? Thanks, Daniel _______________________________________________ Hdf-forum is for HDF software users discussion.
