1. Send Function Function prototype: int send (socket S, char * Buf, int Len, int flags ); Function: both client and server applications use the send function to send data to the other end of the TCP connection. The client program generally uses the

1. send recv is the file descriptor for the set interface.Read write requires a file descriptor. Read and write can also process socket fdThe two are consistent on BSD4.4 and will eventually be tuned to a unified kernel processing function, but the

What is the difference between read () and recv ()?From Andrew Gierth (andrew@erlenstar.demon.co.uk):Read () is equivalent to recv () with a flags parameter of 0. Other values for the flags parameter change the behaviour of recv (). Similarly, write

Send blockingThe socket recv send interface is blocked, which causes the server side not to respond to any requests from the client, so the socket is set to a non-blocking state in general.However, some scenarios, such as ssl_accept, need to use a

In the previous article, we implemented a readn function to read fixed bytes of data to avoid the problem of sticking packets. If the length of each field in the application layer protocol is fixed, it is very convenient to use readn for reading.
