.TH socket_accept4 3

|
|
|
|
.SH NAME
|
|
|
|
|
socket_accept4 \- accept an IPv4 TCP connection on a socket
|
|
|
|
|
.SH SYNTAX
|
|
|
|
|
.B #include <socket.h>
|
|
|
|
|
|
|
|
|
|
int \fBsocket_accept4\fP(int \fIs\fR,char \fIip\fR[4],uint16 *\fIport\fR);
|
|
|
|
|
.SH DESCRIPTION
|
|
|
|
|
When a TCP connection arrives on a listening TCP socket \fIs\fR, the
|
|
|
|
|
socket becomes readable.
|
|
|
|
|
|
|
|
|
|
socket_accept4 accepts the connection. It sets \fIip\fR and \fIport\fR
|
|
|
|
|
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.
