This is common in MPI-IO related patterns, or when growing aĭataset over the course of a simulation. Note: For advanced usecases the dataset can be created without immediately Note: H5File.hpp is the top-level header of HighFive core which should be always included. Because `data` has the correct size, this will // not cause `data` to be reallocated: Read back, with allocating: auto data = dataset. We create an empty HDF55 file, by truncating an existing // file if required:Īuto dataset = file. Std::string filename = "/tmp/new_file.h5 "
