of a PBCallInfo structure is not null, it sets
the value of the pArrayItemCount variable to
the length of the array:

if ( !(ci-&gt;pArgs-&gt;GetAt(0)-&gt;IsNull()) )<br>{<br>&#160;&#160;&#160;array = ci-&gt;pArgs-&gt;GetAt(0)-&gt;GetArray();<br>&#160;&#160;&#160;pArrayInfo = session-&gt;GetArrayInfo (array);<br>&#160;&#160;&#160;pArrayItemCount = session-&gt;<span>GetArrayLength</span>(array);<br>}<br>else<br>{<br>&#160;&#160;&#160;// NULL array<br>pArrayItemCount = 0;<br>}

1	if ( !(ci->pArgs->GetAt(0)->IsNull()) )<br>{<br>   array = ci->pArgs->GetAt(0)->GetArray();<br>   pArrayInfo = session->GetArrayInfo (array);<br>   pArrayItemCount = session-><span>GetArrayLength</span>(array);<br>}<br>else<br>{<br>   // NULL array<br>pArrayItemCount = 0;<br>}
