.TH socket_bind6_reuse 3 |
|
.SH NAME |
|
socket_bind6_reuse \- set the local IP address and port of a socket |
|
.SH SYNTAX |
|
.B #include <socket.h> |
|
|
|
int \fBsocket_bind6_reuse\fP(int \fIs\fR,char \fIip\fR[16],uint16 \fIport\fR, |
|
uint32 \fIscope_id\fR); |
|
.SH DESCRIPTION |
|
socket_bind6_reuse 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_reuse returns 0. If anything goes wrong, |
|
socket_bind6_reuse 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. |
|
|
|
Unlike socket_bind6 this function will also tell the operating system |
|
that the address is to be reused soon, which turns off the normal pause |
|
before this IP and port can be bound again. |
|
.SH EXAMPLE |
|
#include <socket.h> |
|
|
|
int \fIs\fR; |
|
char \fIip\fR[16]; |
|
uint16 \fIp\fR; |
|
|
|
\fIs\fR = socket_tcp4(); |
|
socket_bind6_reuse(s,ip,p); |
|
socket_connect4(s,ip,p); |
