[ts-7000] udp broadcast doesn't work ?

[Dave Cramer <>]

Any ideas why we can't send a udp broadcast message with the  
following code ?

int main( int arc, char *argv[])
{
         int flag=1;
         int sd;
         char testbuff[] = {"1234567890"};
         struct sockaddr_in bcast_addr;

         if ((sd =socket (AF_INET, SOCK_DGRAM, IPPROTO_UDP))==-1)
         {
                 fprintf(stderr,"socket error\n");
                 exit(-1);
         }
         if ( setsockopt(sd,SOL_SOCKET,SO_BROADCAST,(char *) 
&flag,sizeof(flag)) < 0 )
         {
                 fprintf(stderr,"unable to set broadcast\n");
                 exit(-1);
         }
         memset( &bcast_addr,0,sizeof( struct sockaddr_in) );
         bcast_addr.sin_family = AF_INET;
         bcast_addr.sin_addr.s_addr = 0xffffffff;
         bcast_addr.sin_port=5433;
         if ( sendto( sd,testbuff, sizeof( testbuff),0,
                 ( const struct sockaddr * ) &bcast_addr,
                 sizeof( const struct sockaddr_in ) ) == -1)
         {
                 fprintf( stderr, "error sending\n");
                 exit(-1);
         }

         fprintf( stderr,"everything ok\n");


}
