CWTTLogger::TraceMachineInfo
The TraceMachineInfo method logs a trace of the operating system where the test is run.
HRESULT TraceMsg (
LONG hDevice,
LPWSTR pwszUserDefinedData
);
Parameters
hDevice
[in] A handle to the device tracing topology. You can combine multiple handles by using the bitwise OR operator (for example, hDevice1 OR hDevice2).
pwszUserDefinedData
[in] User-defined data. This parameter is ignored in the current version of DTM Logger.
Return Value
TraceMachineInfo returns one of the following values:
- S_OK
The operation was successful. - S_FALSE
The operation was successful but the last device has been detached, which has triggered a rollup. - HRESULT
The operation failed. You should use the FAILED macro to check HRESULT values.
Example
The following code example demonstrates how to use the TraceMachineInfo method.
//
// Collect machine information
//
Log.TraceMachineInfo (
hDevice,
NULL
);
