-/**
- * _cairo_surface_snapshot:
- * @surface: a #cairo_surface_t
- *
- * Make an immutable reference to @surface. It is an error to call a
- * surface-modifying function on the result of this function. The
- * resulting 'snapshot' is a lazily copied-on-write surface i.e. it
- * remains a reference to the original surface until that surface is
- * written to again, at which time a copy is made of the original surface
- * and the snapshot then points to that instead. Multiple snapshots of the
- * same unmodified surface point to the same copy.
- *
- * The caller owns the return value and should call
- * cairo_surface_destroy() when finished with it. This function will not
- * return %NULL, but will return a nil surface instead.
- *
- * Return value: The snapshot surface. Note that the return surface
- * may not necessarily be of the same type as @surface.
