    DWORD                 length,
    IDiaEnumLineNumbers** ppResult
);

Parameters

rva

[in] Specifies the address as an RVA.

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.

Return Value

If successful, returns S_OK; otherwise, returns an error code.

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);
}
