25<H2>Description</H2>
26<P>This function can get a pointer to the current overflow callback that the GD library will invoke when a graphics display list overflows. Overflow is only detected if the current location pointer is or will be past the end of the associated memory buffer when attempting to write to a <a href="GDLObj.html"><CODE>GDLObj</CODE></a>.</P>
27<P>If an overflow callback is not declared, the default overflow process will force an assertion failure. (Debug build only.)</P>
