This function gets the start address of the <a href="../wpad/WPADStatus.html"><code>WPADCLStatus</code></a> structure ring buffer used by that autosampling. <CODE>KPAD_RING_BUFS</CODE> defines the buffer's length. If you want to directly access values in the <a href="../wpad/WPADStatus.html"><code>WPADCLStatus</code></a> structure, appropriate values can be accessed through the joint use of the <a href="../wpad/WPADGetLatestIndexInBuf.html"><code>WPADGetLatestIndexInBuf</code></a> function.
