35<H2>Description</H2>
36<P>This function allows you to declare a callback that is invoked when a graphics display list overflows. Overflow is only detected when you attempt to write to a <a href="GDLObj.html">GDLObj</a> and the current location pointer is (or will be, as a result of the write) past the end of the associated memory buffer.</P>
37<P>If an overflow callback is not declared, the default overflow process will force an assertion failure. (Debug build only.)</P>
