That’s not a good reason not to use it.

A function can be not thread-safe and still safe to use in single-threaded programs.

The point is that strtok is not a good choice even for single-threaded code.

Why isn't it a good choice exactly? Could you sum it up?

Maybe he means that the function is not re-entrant. You cannot run a loop that tokenizes a string, and somewhere inside, you call a function that uses strtok itself. This can happen inadvertently.
