我应该研究哪个 function 在 C 中制作插座？

Question

What function should I look into to create a socket for my mini-ftp server in C in the stdlib, except recv , send and all system calls that make a socket non-blocking?

Answer 1

There are plenty of guides for this sort of thing, in particular see Beej's Guide to Network Programming for working with Linux. There are similar / equivelant APIs exposed in Windows and other operating systems.

Fundamentally though, if you're using Liunx, you'll be interested in:

• socket() to create the socket
• connect() / bind() and listen() to connect or listen
• send() and recv() to send and receive

If you're interested in non-blocking I/O, then the " Blocking " section will help.
