- .SS DESCRIPTION
- .PP
- Device objects are reference counted.
- The \f[C]rtcRetainDevice\f[] function increments the reference count of
- the passed device object (\f[C]device\f[] argument).
- This function together with \f[C]rtcReleaseDevice\f[] allows to use the
- internal reference counting in a C++ wrapper class to manage 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[].
