IDiaDataSourceEx2

Initiates access to a source of debugging symbols and retrieves information about that source.

Syntax

IDiaDataSourceEx2 : IDiaDataSourceEx

Methods in Vtable Order

The following table shows the methods of IDiaDataSourceEx2.

Method Description
IDiaDataSourceEx2::findNamedStreams Retrieves all names of named streams within the datasource that match the optionally given pattern.

Remarks

A call to one of the load methods of the IDiaDataSource interface opens the symbol source. A successful call to the IDiaDataSource::openSession method returns an IDiaSession interface that supports querying the data source. If the load method returns a file-related error, then the IDiaDataSource::get_lastError method return value contains the file name associated with the error.

Notes for Callers

This interface is obtained by calling the CoCreateInstance function with the class identifier CLSID_DiaSource and the interface ID of IID_IDiaDataSourceEx, or by calling QueryInterface on an existing IDiaDataSource interface pointer. The example shows how this interface is obtained.

Example


      IDiaDataSource* pSource;
HRESULT hr = CoCreateInstance(CLSID_DiaSource,
                              NULL,
                              CLSCTX_INPROC_SERVER,
                              IID_IDiaDataSourceEx2,
                              (void**) &pSource);
if (FAILED(hr))
{
    // Report error and exit
}
