The IsEnabled method determines whether logging is enabled.

Syntax

HRESULT IsEnabled(
  [out] BOOL *pfEnabled
);

Parameters

[out] pfEnabled

Pointer to a flag that is true on output if logging is enabled.

Return value

The method returns an HRESULT. All the interface methods in Windows Media Device Manager can return any of the following classes of error codes:

Standard COM error codes
Windows error codes converted to HRESULT values
Windows Media Device Manager error codes

For an extensive list of possible error codes, see Error Codes.

Remarks

The file WmdmLog.idl is the IDL source code for WmdmLog.dll. This file is processed by the MIDL tool to produce the type library (WmdmLog.tlb) and marshaling code.

Examples


// Create logging object.
CoCreateInstance(CLSID_WMDMLogger, NULL, CLSCTX_ALL, __uuidof(IWMDMLogger), (void**)&m_pLogger);
BOOL enabled = FALSE;
hr = m_pLogger->IsEnabled(&enabled);
// TODO: Display a message that logging is either enabled or disabled.
if(!enabled)
{
    if(m_pLogger->Enable(TRUE) != S_OK)
        m_pLogger = NULL;
}
