NAME¶
socket_bind4 - set the local IP address and port of a socket
SYNTAX¶
#include <libowfat/socket.h>
int socket_bind4(int s,char ip[4],uint16 port);
DESCRIPTION¶
socket_bind4 sets the local IP address and TCP/UDP port of a TCP/UDP socket s to ip and port respectively.
If the IP address is 0.0.0.0, the operating system chooses a local IP address. If port is 0, the operating system chooses a port.
Normally socket_bind4 returns 0. If anything goes wrong, socket_bind4 returns -1, setting errno appropriately.
EXAMPLE¶
#include <libowfat/socket.h>
int s;
char ip[4];
uint16 p;
s = socket_tcp4();
socket_bind4(s,ip,p);
socket_connect4(s,ip,p);
