33<P>Whether results were obtained (0) or the matrix stack is busy (not 0).</P>
34<H2>Description</H2>
35<P>Determines whether or not overflow/underflow is generated in the matrix stack. If the value returned is non-zero, current overflow or underflow status cannot be acquired because the matrix stack is busy. If the value returned is zero, whether the matrix stack is overflow or underflow is stored in * overflow.</P>
36<P>If an overflow occurs, this function will return the overflow status until the <CODE><A href="G3X_ResetMtxStackOverflow.html">G3X_ResetMtxStackOverflow</A></CODE> function is called.</P>
