## Remarks

This callback is invoked by the `XtfCaptureOutputBegin` function for each error captured during a capture session. Use this callback function, along with an [XtfDebugStringCallback](/reference/tools/xtf/xtfapi/functions/xtfdebugstringcallback-xtfapi-xbox-windows-m) callback function, to capture general debug output from a development console. If you want to monitor debug output from a specific process ID on a development console, use a debug monitor client. For more information about using a debug monitor client, see [XtfCreateDebugMonitorClient](/reference/tools/xtf/xtfdebugmonitor/methods/xtfcreatedebugmonitorclient-xtfdebugmonitor-xbox-microsoft-m).
