There's also the option to rewrite the C example to accept data via Unix Domain Sockets. Then in your perl script(*), just open a connection and send screen/data updates.

For C: https://www.educative.io/answers/unix-socket-programming-in-c

For Perl: IO::Socket::UNIX

(*) of course, with network code, you have other options for the client as well
