.SH NAME
|
|
|
|
|
socket_accept6 \- accept an IPv6 TCP connection on a socket
|
|
|
|
|
.SH SYNTAX
|
|
|
|
|
.B #include <socket.h>
|
|
|
|
|
|
|
|
|
|
int \fBsocket_accept6\fP(int \fIs\fR,char \fIip\fR[16],uint16 *\fIport\fR,uint32 *\fIscope_id\fR);
|
|
|
|
|
.SH DESCRIPTION
|
|
|
|
|
When a TCP connection arrives on a listening TCP socket \fIs\fR, the
|
|
|
|
|
socket becomes readable.
|
|
|
|
|
|
|
|
|
|
socket_accept6 accepts the connection. It sets \fIip\fR and \fIport\fR
|
|
|
|
|
to the client IP address and client TCP port and \fIscope_id\fR to the
|
|
|
|
|
IPv6 scope ID. 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 \fIscope_id\fR is the null pointer, socket_accept6 will discard the
|
|
|
|
|
scope ID.
|
|
|
|
|
|
|
|
|
|
If something goes wrong, socket_accept6 returns -1, setting errno
|
|
|
|
|
appropriately, without creating a new socket.
