  rtcNewSharedBuffer - creates a new shared data buffer

  #include <embree3/rtcore.h>

  RTCBuffer rtcNewSharedBuffer(
    RTCDevice device,
    void* ptr,
    size_t byteSize
  );

The rtcNewSharedBuffer function creates a new shared data buffer object bound to the specified device (device argument). The buffer object is reference counted with an initial reference count of 1. The buffer can be released using the rtcReleaseBuffer function.

At construction time, the pointer to the user-managed buffer data (ptr argument) including its size in bytes (byteSize argument) is provided to create the buffer. At buffer construction time no buffer data is allocated, but the buffer data provided by the application is used. The buffer data must remain valid for as long as the buffer may be used, and the user is responsible to free the buffer data when no longer required.

The data pointer (ptr argument) must be aligned to 4 bytes; otherwise the rtcNewSharedBuffer function will fail.

On failure NULL is returned and an error code is set that can be queried using rtcGetDeviceError.
