Cancellation points and cancellability state are discussed in the post. In a C codebase that you fully control pthread cancellation _can_ be made to work, but if you control the whole codebase I'd argue you're better off just structuring your program so that you yield cooperatively frequently enough to ensure prompt termination.

Not arguing there. I'm just pointing out that the post's claim that " Thread cancellation is incompatible with modern C++" needs more nuance.
