set socket buffer size for receive and send buffer

How can I set the socket buffer size for a UNIX socket file descriptor in C? I understand setsockopt is probably the system call involved... Can anyone give an example of how to use it, the one's I have found do not explain how to set the buffer size?

Solution

  • On Ubuntu 14.04 Linux check out man 7 socket, and specifically look at SO_RCVBUF and SO_SNDBUF.
