43<h2>Description</h2>
44    <div class="section">
45<p>Switches the camera settings context.</p><P>
46It is faster to switch the context than to configure settings individually.
47            </P><P>
48Because this function replaces the specified camera's settings with the settings of the specified context (A or B), you cannot set the <SPAN class="argument">select</SPAN> argument to <CODE>SELECT_NONE</CODE> or the <SPAN class="argument">next</SPAN> argument to <CODE>CONTEXT_BOTH</CODE>.
49            </P><P>
50The default value is <CODE>CONTEXT_A</CODE> for all cameras.
51</P><p>Note that this function may block internally for an extended period if a camera is restarting.</p></div>
