[P4-dev] A beginner's question about p4 calling C library functions

Hi, everybody,

I am a P4 newbie and I have a simple question about P4: It seems to me that
doing arbitrary arithmetic operations or string comparisons is not well
supported in P4 (correct me if I am wrong). So is it possible in P4 to call
external C library functions?

Thanks for your help in advance.

Best
Chang
