# rtcRetainBVH(3embree4)

### NAME

-

  ```
  rtcRetainBVH - increments the BVH reference count
  ```

### SYNOPSIS

-

  ```
  #include <embree4/rtcore.h>
  void rtcRetainBVH(RTCBVH bvh);
  ```

### DESCRIPTION

BVH objects are reference counted. The `rtcRetainBVH` function increments the reference count of the passed BVH object (`bvh` argument). This function together with `rtcReleaseBVH` allows to use the internal reference counting in a C++ wrapper class to handle the ownership of the object.

### EXIT STATUS

On failure an error code is set that can be queried using `rtcGetDeviceError`.
