These changes are fine, but of very little consequence. Note it s done at (FPM) startup time not runtime.

This looks unnecessary. In these cases, the compiler can infer status and ping don't change in the loop body, and as such will move the strlen() out of the loop. See https://en.wikipedia.org/wiki/Loop-invariant_code_motion.
