HRESULT findLinesByVA ( 
   ULONGLONG             va,
   DWORD                 length,
   IDiaEnumLineNumbers** ppResult
);

Parameters

  • va
    [in] Specifies the address as a VA.

  • length
    [in] Specifies the number of bytes of address range to cover with this query.

  • ppResult
    [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);
}
