why read only ?

Is this a copy/paste mistake, or am I missing something ? https://github.com/nkg114mc/c-gomoku-cli/blob/main/src/engine.cpp#L180

Thanks for pointing out, I didn't notice it at all. It should be _O_WRONLY.

I guess the reason it runs with no problem is that value of _O_RDONLY constant equals 0, so it actually becomes _O_TEXT in this case, which is a valid flag to the API.

In fact, I found that _open_osfhandle in windows CRT doesn't care about _O_RDONLY or _O_WRONLY at all, mentioned here... (not even documented in MSDN 😢)
