Example

This example shows a function that obtains all line numbers contained in the specified function using the function's relative virtual address and length.

IDiaEnumLineNumbers* GetLineNumbersByRVA(IDiaSymbol *pFunc, IDiaSession *pSession)
{
    IDiaEnumLineNumbers* pEnum = NULL;
    DWORD                rva;
    ULONGLONG            length;

    if (pFunc->get_relativeVirtualAddress ( &rva ) == S_OK)
    {
        pFunc->get_length ( &length );
        pSession->findLinesByRVA( rva, static_cast<DWORD>( length ), &pEnum );
    }
    return(pEnum);
