<p>The Receive Response (QzdmReceiveResponse) API is used to receive an acknowledgement and the response data over an OptiConnect path. A maximum of 32KB of data may be received in a single receive response.</p>
|
||
|
|
|
||
|
|
<p>The response data is received into the output buffers, which were previously defined in the output descriptors on the Send Request (QzdmSendRequest) API.</p>

<h3>Restrictions</h3>
|
||
|
|
|
||
|
|
<p>The following restrictions apply:</p>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>The OptiConnect QSOC subsystem must be started on both the local and remote systems prior to calling this API.<br><br>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li>A stream must be opened to the OptiConnect device driver on the local system by using the Open Stream (QzdmOpenStream) API prior to calling this API.<br><br>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li>A path must be opened to the remote system by using the Open Path (QzdmOpenPath) API prior to calling this API.<br><br>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li>If the receiving system does not provide a large enough data buffer to receive all of the data, the data that will fit into the data buffer is moved, but the remaining data is truncated. The user must then increase the size of the data buffer, and then retry the entire transaction.<br><br>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li>A maximum of 16 transactions may be in progress for a stream-identifier and path-identifier pair.</li>
|
||
|
|
</ul>

<h3><a name="HDRRRSPFLD">Field Descriptions</a></h3>
|
||
|
|
|
||
|
|
<p><strong>Acknowledgement data.</strong> The acknowledgement data for the request. This field is provided as input on the Send Response (QzdmSendResponse) API.</p>
|
||
|
|
|
||
|
|
<p><strong>Actual response data length.</strong> The actual length that was received for the response data. If the response data that was sent from the Send Response (QzdmSendResponse) API is larger than the buffer that was provided with the Send Request (QzdmSendRequest) API, not all of the data was received. It is the responsibility of the user's application program to retry the entire transaction by using a larger data buffer size for the Send Request (QzdmSendRequest) API to receive all of the data with the Receive Response (QzdmReceiveResponse) API.</p>
|
||
|
|
|
||
|
|
<p><strong>Path identifier.</strong> The OptiConnect path that is used for communications. This field is provided as output on the Open Path (QzdmOpenPath) API.</p>
|
||
|
|
|
||
|
|
<p><strong>Stream identifier.</strong> The OptiConnect stream that is used for communications. This field is provided as output on the Open Stream (QzdmOpenStream) API.</p>
|
||
|
|
|
||
|
|
<p><strong>Time-out value.</strong> A length of time, in milliseconds, to wait for the Receive Response (QzdmReceiveResponse) API to complete. If the Receive Response (QzdmReceiveResponse) API does not complete before the specified time-out value, the exception CPFADFE is returned. The user should then re-issue the Receive Response (QzdmReceiveResponse) API and specify the same time-out value or an increased time-out value.</p>
|
||
|
|
|
||
|
|
<p>The Receive Response (QzdmReceiveResponse) API remains outstanding, and control is not returned to the user application until either of the following occurs:</p>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>The request either completes successfully or unsuccessfully.</li>
|
||
|
|
|
||
|
|
<li>The time-out value has been exceeded.</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p>A value of -1 may be specified, which indicates to wait forever for the Receive Response (QzdmReceiveResponse) API to complete.</p>
|
||
|
|
|
||
|
|
<p><strong>Transaction identifier.</strong> The specific transaction associated with this Receive Response (QzdmReceiveResponse) API. This field is provided as output on the Send Request (QzdmSendRequest) API.</p>
