.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. |
|
|
|
.SH EXAMPLE |
|
#include <socket.h> |
|
|
|
int \fIs\fR; |
|
char \fIip\fR[4]; |
|
uint16 \fIp\fR; |
|
|
|
\fIs\fR = socket_tcp(); |
|
socket_bind4(s,ip,p); |
|
socket_connect4(s,ip,p); |
