.SS DESCRIPTION
.PP
The \f[C]rtcSetGeometryUserData\f[] function sets the user\-defined data
pointer (\f[C]userPtr\f[] argument) for a geometry (\f[C]geometry\f[]
argument).
This user data pointer is intended to be pointing to the
application\[aq]s representation of the geometry, and is passed to
various callback functions.
The application can use this pointer inside the callback functions to
access its geometry representation.
.PP
The \f[C]rtcGetGeometryUserData\f[] function can be used to query an
already set user data pointer of a geometry.
.SS EXIT STATUS
.PP
On failure an error code is set that can be queried using
\f[C]rtcGetDeviceError\f[].
