Estoy intentando enviar un SOCK_DGRAM por broadcast a una direcci�n IP
255.255.255.255 con una mascara de subred  255.255.0.0.

Es posible hacerlo ? A una x.x.255.255 puedo hacerlo.

// SOCKET for sending

// Opens the Logic Channel (UDP->linkaje fragil)

// nLogicCh_Write = socket ( AF_INET, SOCK_DGRAM, IPPROTO_UDP );

if ( nLogicCh_Write == -1 ) {

    // Sock Ini FAILED on socket WT creation

    // Closes the Logical Channel to read

    close( nLogicCh_Read );

    return FALSE;

}

// Fills the Socket Descriptor

ssiWrite.sin_family = AF_INET;

ssiWrite.sin_addr.s_addr = inet_addr( "255.255.255.255" );

ssiWrite.sin_port = htons( STATEMACHINE_RECONFIGURADOR_COMM_PORT );

if ( setsockopt( nLogicCh_Write, SOL_SOCKET, SO_BROADCAST, &one,
sizeof(one)) != 0 ) {

    // Sock Ini FAILED on socket WT creation

}

nSentDataLen = sendto( nLogicCh_Write, aszUnitIDRqstMsg, nMsgLen, 0, (struct
sockaddr *)&ssiWrite, sizeof(struct sockaddr) );

if ( nSentDataLen != nMsgLen ) //ERROR
