Is connect() necessary if I want only to receive data in C/TCP?

if I want ONLY to receive data from a client, and not send data out, is it necessary have a connect() in the code of my server?

Or is it sufficient to have the following?

socket();
bind();
listen();
accept();
Solution

  • This describes the basic principle of server-client interaction. As you can see, the client must connect to the server before any interaction.

    Once you've built a socket descriptor with the socket() call, you can connect that socket to a remote server using the well-named connect() system call.

    Also the sequence you mentioned is in the server. If you want to only receive data from server, just do the read in client and write in server. But connect is neccessary.
