4. Accept connection

Code: int accept (int sockfd,struct sockaddr addr,socklen_t addrlen)

4.2 Parameter comment

4.2.2 addr: used to obtain the remote socket address of the accepted connection. The length is the next parameter addlen.

In the case of client disconnection mentioned in the previous article, the supplementary code is now available.

Int main (int argc,char * argv []) {if (argc=0); / / use assertions to create code that is more stable, of better quality, and less error-prone. You can use assertions when you need to interrupt the current operation when a value is FALSE. Unit tests must use Junit/JunitX. Int ret = bind (sock, {struct sockaddr*} & address,sizeof (address)); assert (retinue 1); ret = listen (sock,5); assert (ret! = 1); sleep (20); / / wait 20 seconds for the client connection and related operations to complete struct sockaddr_in client; socklen_t client_addrlength = sizeof (client); int connfd = accept (sock, {struct sockaddr*} & client,&client_addrlength); if (connfd)
