<h1>List of HDF5 VFL Functions</h1>
<pre>
The following functions support the HDF5 virtual file layer (VFL), enabling
the creation of customized I/O drivers.
At this time, these functions are documented only in the <a href="VFL.html">HDF5 Virtual File
Layer</a> design document and in the source code.
