27<H2>Description</H2>
28<P>This function returns a nonzero value if rendering is not in time for display and the color buffer underflows (that is, the rendering engine has a line overflow). Once an underflow occurs, a nonzero value will continue to be returned until the <CODE><A href="G3X_ResetLineBufferUnderflow.html">G3X_ResetLIneBufferUnderflow</A></CODE> function is called.</P>
