<p>The Retrieve PEX Information (QypeRetrievePexInformation) API retrieves information about a PEX session. It can be used to retrieve the following:</p>
<ul>
<li>Session name</li>
<li>Collection type</li>
<li>State</li>
<li>State qualifier</li>
<li>Event count</li>
<li>Filtered event count</li>

<h3>Required Parameter Group</h3>
<dl>
<dt><strong>Receiver variable</strong></dt>
<dd>OUTPUT; CHAR(*)
<p>The variable that is to receive the information requested. The minimum size
for this area is 8 bytes. You can specify the size of this area to be smaller
than the format requested if you specify the length of receiver variable
parameter correctly. As a result, the API returns only the data that the area
can hold.</p>
</dd>
<dt><strong>Length of receiver variable</strong></dt>
<dd>INPUT; BINARY(4)
<p>The length of the receiver variable. If this value is larger than the actual
size of the receiver variable, the results may not be predictable. The minimum
value is 8.</p>
</dd>
<dt><strong>Format name</strong></dt>
<dd>INPUT; CHAR(8)
<p>The content and format of the information returned for the PEX session.</p>
<p>The possible format names are:</p>
