  26 <h3>DESCRIPTION</h3>
  27 <p>
  28 The <strong>host_kernel_version</strong> function returns the version
  29 string compiled into the
  30 kernel executing on <var>host</var> at the time it was built.  This describes
  31 the version of the kernel.  The constant <strong>KERNEL_VERSION_MAX</strong> (in
  32 \*L<mach/host_info.h>\*O)
  33 should be used to dimension storage for the returned string if the
  34 <var>kernel_version_t</var> declaration is not used.
