You’re doing it again here; shooting first, aiming last. Maybe you should ignore some questions.
As for my “direct question”, you’ve conveniently stripped it of its important context. It was in response to your comment that checking for purge flags was an acceptable way to flush a string buffer. For this purpose, it’s a lame workaround and that’s being polite.
Most bizarre of all is your continued persistence that I should consider “exploring approaches that do not require clearing the buffer but accomplishes the same thing”. Yes, erase the received string without erasing it. I’ll get right on that.
