Write a client-server program in C ... on a piece of paper

Question

It was an interview question. o_O

Leave aside the questions asking such a question in the interview.

I am wondering what alternatives to the TCP TCP socket approach are readily available (e.g. libraries) for use in C or C ++.

I do not make any assumptions on the platform, compiler, etc. - make a choice.

I do not ask you guys to write a program, but simply point out the technologies that can be used for this purpose, and, perhaps, with an example or a tutorial using this technology in C / C ++.
