.SS DESCRIPTION
.PP
BVH objects are reference counted.
The \f[C]rtcRetainBVH\f[] function increments the reference count of the
passed BVH object (\f[C]bvh\f[] argument).
This function together with \f[C]rtcReleaseBVH\f[] allows to use the
internal reference counting in a C++ wrapper class to handle the
ownership of the object.
.SS EXIT STATUS
.PP
On failure an error code is set that can be queried using
\f[C]rtcGetDeviceError\f[].
