# H5_CLOSE

The H5_CLOSE procedure flushes all data to disk, closes file identifiers, and cleans up memory. This routine closes IDL’s link to its HDF5 libraries. This procedure is used automatically by IDL when RESET_SESSION is issued, but it may also be called if the user desires to free all HDF5 resources.
