NAME

       socket_mcloop4 - set multicast loopback

SYNTAX

       #include <socket.h>

       int socket_mcloop4(int s,char loop);

DESCRIPTION

       socket_mcloop4  activates  multicast  loopback  for  the socket s if loop is non-zero, and
       deactivates it otherwise.  If loopback is activated, packets sent on this socket  will  be
       received on the same host.

       If something goes wrong, socket_mcloop4 returns -1, setting errno appropriately.
