The following functions support the HDF5 virtual file layer (VFL), enabling the creation of customized I/O drivers. At this time, the H5FD functions are documented only in the HDF5 Virtual File Layer design document and in the source code. H5Pset_driver and H5Pget_driver_info are documented in the HDF5 Reference Manual.
