This function blocks the process until a connection request from a remote
host arrives on the TCP connection conn. The
connection must be in the LISTEN state so netconn_listen()
must be called prior to netconn_accept(). When a
connection is established with the remote host, a new connection structure
is returned.
Example 4-1. This example shows how to open a TCP server on port 2000
Note: This is only an example for illustrative purposes, and a complete version should perform comprehensive error checking.
int
main()
{
struct netconn *conn, *newconn;
/* create a connection structure */
conn = netconn_new(NETCONN_TCP);
/* bind the connection to port 2000 on any local IP address */
netconn_bind(conn, NULL, 2000);
/* tell the connection to listen for incoming connection requests */
netconn_listen(conn);
/* block until we get an incoming connection */
newconn = netconn_accept(conn);
/* do something with the connection */
process_connection(newconn);
/* deallocate both connections */
netconn_delete(newconn);
netconn_delete(conn);
}
