37<P>
38Shuts down the wireless hardware and stops the power to the WM. If the return value is <code>WM_ERRCODE_OPERATING</code>, a callback is generated after the shutdown process completes. This function can only be called when the WM is in the <a href="wm_state_diagram.html"><code>IDLE</code></a> state. As a result of this function, the state changes to <a href="wm_state_diagram.html"><code>STOP</code></a>. Use the <A href="WM_Disable.html"><code>WM_Disable</code></A> function after this to return the wireless hardware to the disabled state.
