Methods in Vtable Order

The following table shows the methods of IDiaEnumDebugStreams.

Method	Description
IDiaEnumDebugStreams::get__NewEnum	Retrieves the `IEnumVARIANT` version of this enumerator.
IDiaEnumDebugStreams::get_Count	Retrieves the number of debug streams.
IDiaEnumDebugStreams::Item	Retrieves a debug stream by means of an index.
IDiaEnumDebugStreams::Next	Retrieves a specified number of debug streams in the enumeration sequence.
IDiaEnumDebugStreams::Skip	Skips a specified number of debug streams in an enumeration sequence.
IDiaEnumDebugStreams::Reset	Resets an enumeration sequence to the beginning.
IDiaEnumDebugStreams::Clone	Creates an enumerator that contains the same enumeration state as the current enumerator.

Remarks

The content of debug streams is implementation-dependent and the data formats are undocumented.

Notes for Callers

Call the IDiaSession::getEnumDebugStreams method to obtain an IDiaEnumDebugStreams object.

Example

This example shows how to access the data streams available from this interface. See the IDiaEnumDebugStreamData interface for an implementation of the PrintStreamData function.

void DumpAllDebugStreams( IDiaSession* pSession)
{
    IDiaEnumDebugStreams* pEnumStreams;

    wprintf(L"\n\n*** DEBUG STREAMS\n\n");
    // Retrieve an enumerated sequence of debug data streams
    if(pSession->getEnumDebugStreams(&pEnumStreams) == S_OK)
    {
        IDiaEnumDebugStreamData* pStream;
        ULONG celt = 0;

        for(; pEnumStreams->Next(1, &pStream, &celt) == S_OK; pStream = NULL)
        {
            PrintStreamData(pStream);
            pStream->Release();
        }
        pEnumStreams->Release();
    }
    else
    {
        wprintf(L"Failed to get any debug streams!\n");
    }
    wprintf(L"\n");
}
