## CDisp Class

The CDisp 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)))

CDisp::CDisp

CDisp Class

Constructs a CDisp object.

CDisp(
LONGLONG ll,
int Format = CDISP_HEX
);
CDisp(
REFCLSID clsid
);
CDisp(
double d
);
CDisp(
CRefTime t
);
CDisp(
IPin *pPin
);

##### Parameters

ll
  LONGLONG value for display.
Format
  Whether the value should be displayed in decimal (CDISP_DEC) or (by default) hexadecimal (CDISP_HEX).
clsid
  Class identifier to display.
d
  The double value to display.
t
  Reference time to display. Note that passing a value of type REFERENCE_TIME will use the LONGLONG constructor.
pPin
  IPin interface to display a pin as "CLSID of the filter(Pin name)"; for example, CLSID_AudioRenderer(Audio Input Pin).

##### Return Values

No return value.

##### Remarks

Various constructors are provided, which allows information to be displayed in the most suitable way.

###

CDisp::LPCTSTR

CDisp Class

Casts the CDisp object to an LPCTSTR value for use in a debug string.

    operator LPCTSTR();

##### Return Values

Returns the string representation of the variable used in the constructor.
