51<P>This function returns coefficients used in the lighting attenuation calculation for a given light object.&nbsp;The application must allocate memory for the light object.&nbsp;The coefficients <SPAN class="argument">k0</SPAN>, <SPAN class="argument">k1</SPAN>, and <SPAN class="argument">k2</SPAN> are used for distance attenuation.&nbsp;These parameters can be set using the <A href="GXInitLightAttn.html"><CODE>GXInitLightAttn</CODE></A>, <A href="GXInitLightAttnK.html"><CODE>GXInitLightAttnK</CODE></A>, <A href="GXInitLightDistAttn.html"><CODE>GXInitLightDistAttn</CODE></A> or <A href="GXInitLightShininess.html"><CODE>GXInitLightShininess</CODE></A> function.</P>
