<p>The Retrieve Low-Level Environment Window Mode (QsnRtvEnvWinMod) API queries
the state of the window mode for the low-level interfaces.</p>
<br>
<h3>Authorities and Locks</h3>
<p>None</p>
<br>
<h3>Required Parameter Group</h3>
<dl>
<dt><strong>Window mode description</strong></dt>
<dd>OUTPUT; CHAR(*)
<p>The field in which the window mode description should be stored. The format
of the data returned in this field is described in <a href="#HDRFDRTD1">Format
of the Data Returned</a>.</p>
</dd>
<dt><strong>Length of window mode description</strong></dt>
<dd>INPUT; BINARY(4)
<p>The length of the window mode description parameter. If the length is larger
than the size of the receiver variable, the results are not predictable. The
minimum length is 8. The API returns as much information as it can fit in this
length. If the available information is longer, it is truncated. If the
available information is shorter, the unused output is unchanged; whatever is
already stored in that space remains there. To determine how much information
the API actually returns in response to this call, see the bytes returned
field. To determine how much information the API could return if space were
available, see the bytes available field.</p>
</dd>
</dl>
<br>
<h3>Omissible Parameter Group</h3>
<dl>
<dt><strong>Low-level environment handle</strong></dt>
<dd>INPUT; BINARY(4)
<p>The low-level environment that the operation applies to. If this parameter
is omitted or given with a value of zero, the default low-level environment is
used.</p>
</dd>
<dt><strong>Error code</strong></dt>
<dd>I/O; CHAR(*)
<p>The structure in which to return error information. For the format of the
structure, see <a href="../apiref/error.htm#hdrerrcod">Error Code Parameter</a>. If this
parameter is omitted, diagnostic and escape messages are issued to the
application.</p>
</dd>
</dl>
<br>
<h3>Returned Value</h3>
<dl>
<dt><strong>Return code</strong></dt>
<dd>OUTPUT; BINARY(4)
<p>A return code indicating the result of the operation. The value returned
will be 0 if the operation was successful, or -1 otherwise.</p>
</dd>
</dl>
