CDisp Class (Windows Embedded CE 6.0)

1/6/2010

This class provides methods for displaying a number of data types for debugging. It provides a constructor for each type, and can be cast to the LPCTSTR type for use as a string in a debug statement.

For example, the following code fragment

int MyFunc(REFERENCE_TIME rt, IPin *pPin)
{
    DbgLog((LOG_TRACE, 2, TEXT("MyFunc(%s, %s)"),
        (LPCTSTR) CDisp(CRefTime(rt)),
        (LPCTSTR) CDisp(pPin)));
...
}

could output the following reference time and pin information onto the debug log.

Quartz.dll(tid d7) : MyFunc(1.003 sec,
    CLSID_AudioRender(Audio Input pin (rendered)))
