| 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
}
