NAME

       xs_msg_init - initialise empty Crossroads message

SYNOPSIS

       int xs_msg_init (xs_msg_t *msg);

DESCRIPTION

       The xs_msg_init() function shall initialise the message object referenced by msg to
       represent an empty message. This function is most useful when called before receiving a
       message with xs_recv().

           Caution
           Never access xs_msg_t members directly, instead always use the xs_msg family of
           functions.

           Caution
           The functions xs_msg_init(), xs_msg_init_data() and xs_msg_init_size() are mutually
           exclusive. Never initialize the same xs_msg_t twice.

RETURN VALUE

       The xs_msg_init() function shall return zero if successful. Otherwise it shall return -1
       and set errno to one of the values defined below.

ERRORS

       No errors are defined.

EXAMPLE

       Receiving a message from a socket.

           xs_msg_t msg;
           rc = xs_msg_init (&msg);
           assert (rc == 0);
           rc = xs_recv (socket, &msg, 0);
           assert (rc == 0);
