NAME

       socket_bind4_reuse - set the local IP address and port of a socket

SYNTAX

       #include <libowfat/socket.h>

       int socket_bind4_reuse(int s,char ip[4],uint16 port);

DESCRIPTION

       socket_bind4_reuse  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_reuse  returns  0.  If anything goes wrong, socket_bind4_reuse returns -1, setting
       errno appropriately.

       Unlike socket_bind4 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.

EXAMPLE

         #include <libowfat/socket.h>

         int s;
         char ip[4];
         uint16 p;

         s = socket_tcp4();
         socket_bind4_reuse(s,ip,p);
         socket_connect4(s,ip,p);
