• The variable “exiting” should use the data type “sig_atomic_t”.
• The function “exit” does not belong to the list of async-signal-safe functions.
  I guess that a different program design will be needed for your function “sigint_handler”.

Are there any real-world implications due to that?
The only signal handler purpose is to exit the program. Even if it could not be de-initialized successfully for some reason, WinDivert should clean up everything upon process termination.

I don't as long as it works. This is a non-portable application anyway.
