# rtcGetGeometryBufferData(3embree4)

### NAME

-

  ```
  rtcGetGeometryBufferData - gets pointer to
    the first buffer view element
  ```

### SYNOPSIS

-

  ```
  #include <embree4/rtcore.h>
  void* rtcGetGeometryBufferData(
    RTCGeometry geometry,
    enum RTCBufferType type,
    unsigned int slot
  );
  ```

### DESCRIPTION

The `rtcGetGeometryBufferData` function returns a pointer to the first element of the buffer view attached to the specified buffer type and slot (`type` and `slot` argument) of the geometry (`geometry` argument).

If the device associated with `geometry` is a SYCL device, the returned pointer only accessible on the host. The function `rtcGetGeometryBufferDataDevice` can be used to get a pointer accessible on the SYCL device. #### EXIT STATUS

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