NAME¶
socket_accept4 - accept an IPv4 TCP connection on a socket
SYNTAX¶
#include <socket.h>
int
socket_accept4(int
s,char
ip[4],uint16 *
port);
DESCRIPTION¶
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.
EXAMPLE¶
#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);
