rtcRetainDevice - increments the device reference count
#include <embree3/rtcore.h> void rtcRetainDevice(RTCDevice device);
Device objects are reference counted. The rtcRetainDevice function increments the reference count of the passed device object (device argument). This function together with rtcReleaseDevice allows to use the internal reference counting in a C++ wrapper class to manage the ownership of the object.
On failure an error code is set that can be queried using rtcGetDeviceError.
