Does it leak memory or not?

Name: Anonymous 2012-01-05 11:29

I am unfamiliar with the function itself but here is what the manual page on my computer said it did.

The inet_ntoa() function converts the Internet host address in, given in network byte order, to  a  string  in  IPv4 dotted-decimal notation.  The string is returned in a statically allocated buffer, which subsequent calls will over‐write.

No standard functions should leak memory. Stupid question.

No standard functions should leak memory.
How was it stupid?

By which standard? POSIX? Uhh... wait, never mind, I don't wanna know. Seriously. I'm afraid that your uneducated response might give me brain damage.

Use inet_ntop for threads' sake

The return value of inet_ntoa() may point to static data that may be overwritten by subsequent calls to inet_ntoa().
So it depends on whether the function uses static data or allocates memory each time.

It was stupid in the sense that you didn't properly perceive the obvious fact that no one will design a function which intentionally leaks memory.

But it was not excessively stupid. Maybe it was just some lack of attention. Please don't get offended by it.

Yes. Tip: POSIX is a standard.

Don't worry about extending your brain damage. By your general presentation you seem to be already heavily afflicted.

good luck kodak-san. see it as an opportunity for something new. I'm sure you'll land on your feet somewhere, is on the tile flow of a bathroom, scrubbing toilets.

I think Kodak-san is cute, he's like an adorable mascot.

Perhaps he's asking whether it returns a pointer to dynamically allocated memory, in which case not deallocating it would lead to a memory leak.

The answer is no.

The answer is implementation dependent.

No, because the standard clearly says that it is allocated to a static buffer.

I'm not going to bother calling you any names since you probably just missed the answer in >>13, the standard says that it may be allocated in a static buffer, whether it really does so is up to the implementation.

The manual page excerpt in >>2 is the manual page of a specific implementation in which they decided to statically allocate the buffer.

My bad. Strange that they would leave it up to the implementation.  Makes portability a huge pain.
