socket_accept4(3) Library Functions Manual socket_accept4(3)


socket_accept4 - accept an IPv4 TCP connection on a socket


#include <socket.h>

int socket_accept4(int s,char ip[4],uint16 *port);


When a TCP connection arrives on a listening TCP socket s, the socket becomes readable.

socket_accept4 accepts the connection. It sets ip and port to the client IP address and client TCP port. It creates a new socket for the connection, and returns a file descriptor pointing to the new socket; you can use the read and write system calls to transmit data through that file descriptor.

If something goes wrong, socket_accept4 returns -1, setting errno appropriately, without creating a new socket.


#include <socket.h>

int s; char ip[4]; uint16 p;

s = socket_tcp4(); socket_bind4(s,ip,p); socket_listen(s,16); socket_accept4(s,ip,&p);
