[out] Returns an IDiaEnumLineNumbers object that contains a list of all the line numbers that cover the specified address range.

Example

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

IDiaEnumLineNumbers *GetLineNumbersByVA(IDiaSymbol *pFunc, IDiaSession *pSession)  
{  
    IDiaEnumLineNumbers* pEnum = NULL;  
    ULONGLONG            va;  
    ULONGLONG            length;  
  
    if (pFunc->get_virtualAddress ( &va ) == S_OK)  
    {  
        pFunc->get_length( &length );  
        pSession->findLinesByVA( va, static_cast<DWORD>( length ), &pEnum );  
    }  
    return(pEnum);
