.SH NAME

socket_bind6 \- set the local IP address and port of a socket
|

.SH SYNTAX

|
|
|
.B #include <libowfat/socket.h>
|
|
|
|
|
|
|
|
|
|
int \fBsocket_bind6\fP(int \fIs\fR, char \fIip\fR[16], uint16 \fIport\fR,
|
|
|
|
|
uint32 \fIscope_id\fR);
|
|
|
|
|
.SH DESCRIPTION
|
|
|
|
|
socket_bind6 sets the local IP address and TCP/UDP port of a TCP/UDP
|
|
|
|
|
socket \fIs\fR to \fIip\fR and \fIport\fR respectively.
|
|
|
|
|
|
|
|
|
|
If the IP address is ::, the operating system chooses a local IP
|
|
|
|
|
address. If \fIport\fR is 0, the operating system chooses a port.
|
|
|
|
|
|
|
|
|
|
Normally socket_bind6 returns 0. If anything goes wrong, socket_bind6
|
|
|
|
|
returns -1, setting errno appropriately.
|
|
|
|
|
|
|
|
|
|
The \fIscope_id\fR should normally be zero, but for link-local addresses
|
|
|
|
|
it specifies the interface number on which to bind. The interface
|
|
|
|
|
number for a given network interface name can be found with
|
|
|
|
|
\fBsocket_getifidx\fR.
