If I do a `typedef` in C or C++, when should I add `_t` at the end of typedef'ed type? [duplicate]

Answer 1

I personally despise the _t convention. So long as you are consistent, it really does not matter, however.

Note that (as other answers here indicate) if you are coding to some other standard, such as POSIX, you need to check if it's okay in that standard before using such names.
