<p>The Retrieve Call Stack (QWVRCSTK) API returns the call stack information
for the specified thread. The first call stack entry returned corresponds to
the most recent call in the thread.</p>
<br>
<h3>Authorities and Locks</h3>
<dl>
<dt><em>Job Authority</em></dt>
<dd>The API must be called within the thread for which the call stack is being
retrieved, or the caller of the API must be running under a user profile that
is the same as the job user identity of the job containing the thread for which
the call stack is being retrieved. Otherwise, the caller of the API must be
running under a user profile that has job control (*JOBCTL) special authority
or GUI thread control authority.
<p>The <strong>job user identity</strong> is the name of the user profile by
which a job is known to other jobs. It is described in more detail in the
<a href="../rzaks/rzaks1.htm">Work Management</a> topic.</p>
<p><img src="delta.gif" alt="Start of change">
The caller of the API must have service (*SERVICE) special authority to
retrieve advanced details for format CSTK0300.

</dd>
</dl>
<br>
<h3>Required Parameter Group</h3>
<dl>
<dt><strong>Receiver variable</strong></dt>
<dd>OUTPUT; CHAR(*)
<p>The receiver variable that receives the information requested. You can
specify the size of the area to be smaller than the format requested as long as
you specify the length parameter correctly. As a result, the API returns only
the data that the area can hold. For example, this may mean that the value in
the number of call stack entries returned field doesn't match the value in the
number of call stack entries for thread field.</p>
</dd>
<dt><strong>Length of receiver variable</strong></dt>
<dd>INPUT; BINARY(4)
<p>The length of the receiver variable provided. The length of receiver
variable parameter may be specified up to the size of the receiver variable
specified in the user program. If the length of receiver variable parameter
specified is larger than the allocated size of the receiver variable specified
in the user program, the results are not predictable. The minimum length is 8
bytes.</p>
</dd>
<dt><strong>Format of receiver information</strong></dt>
<dd>INPUT; CHAR(8)
<p>The format of the information returned in the receiver variable. The
possible format name is:</p>
