  1. How does closing a file affect open objects

    An object (dataset, group, attribute, named datatype) in an HDF5 file can be opened, and it can be opened more than once. When an object is opened, the HDF5 library returns a unique identifier to the application. Every object that is opened must be closed. If an object was opened more than once, each identifier

  2. Excessive memory usage and file issues due to objects being left open

    Leaving objects open in an HDF5 application can cause excessive memory usage and potentially corrupt an HDF5 file. If objects in an HDF5 file (group, dataset, attribute, ...) are not closed, then the file does not get closed, which can cause problems. If secondary objects (dataspaces, property lists ...) are left open

    identifier. An object's location identifier is returned to an application after the object is opened. To open an object, an application uses a function with three parameters: the location identifier of an already opened object, a path from the already opened object to the object that will be opened, and a property list

  4. Why does re-opening an HDF5 file that is already open with an external link fail, when the file was originally opened with H5F_CLOSE_STRONG?

    there is no identifier for such a file and the file is being kept open by objects in it. If an external link were allowed to open an object with the strong file close degree, then all open objects in that file would be immediately closed when that object is closed. This behavior would be surprising or unexpected to some users. For more
