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]. .SS SEE ALSO .PP [rtcNewBuffer], [rtcReleaseBuffer]
