@d99kris If you want to keep your typedef, I suggest to move it into your rapidcsv namespace. That should avoid conflicts with potential typedefs in other headers.

Thanks for checking the PR @Sven-HP!
This issue should be fixed now. Please let me know if you still encounter any issues @p0358. Thanks.

Hi @p0358 - thanks for reporting the bug. It's an interesting problem! While checking #ifndef ssize_t
will work in this particular scenario, I believe it will not work if another header has typedef
'ed ssize_t
to something else.
Actually ssize_t
is mostly used internally in rapidcsv
and not exposed much in the public API. I'm wondering if maybe it makes sense to replace it with int64_t
to avoid the problem altogether. I'll need to do some research and get back.

Thanks for the suggestion @Sven-HP - that is true! But I think I'm more inclined to drop the typedef and simply use a standard integer type. I'd prefer if portable apps would not need stuff like rapidcsv::ssize_t x = doc.GetColumnIdx("name");
when they do interact with an API exposing the type.
I've been thinking about which type to use, and I think regular int
will do. For CSV files with over 2 billion rows or columns it probably becomes impractical to use rapidcsv anyway (as rapidcsv keeps the entire parsed CSV in memory so the memory usage would be... quite high..). int64_t
would be a safer choice, but it has performance impact on 32-bit environments.

I've created a PR #139 for switching ssize_t usage to int. Feel free to provide feedback on the change in the review. If there are no major concerns I will proceed to merge it next weekend probably.
