.SS DESCRIPTION
.PP
Buffer objects are reference counted.
The \f[V]rtcRetainBuffer\f[R] function increments the reference count of
the passed buffer object (\f[V]buffer\f[R] argument).
This function together with \f[V]rtcReleaseBuffer\f[R] 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[V]rtcGetDeviceError\f[R].
