\f[C]
#include <embree4/rtcore.h>

void* rtcGetGeometryUserData(RTCGeometry geometry);

.SS DESCRIPTION
.PP
The \f[V]rtcGetGeometryUserData\f[R] function queries the user data
pointer previously set with \f[V]rtcSetGeometryUserData\f[R].
When \f[V]rtcSetGeometryUserData\f[R] was not called yet, \f[V]NULL\f[R]
is returned.
.PP
This function is supposed to be used during rendering, but only
supported on the CPU and not inside SYCL kernels on the GPU.
Inside a SYCL kernel the \f[V]rtcGetGeometryUserDataFromScene\f[R]
function has to get used.
.SS EXIT STATUS
.PP
On failure an error code is set that can be queried using
\f[V]rtcGetDeviceError\f[R].
