NAME

zmq_msg_init - initialise empty 0MQ message

CONTENTS

SYNOPSIS

int zmq_msg_init (zmq_msg_t *msg);

DESCRIPTION

The zmq_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 zmq_recv().

Caution

Never access zmq_msg_t members directly, instead always use the zmq_msg family of functions.

Caution

The functions zmq_msg_init(), zmq_msg_init_data() and zmq_msg_init_size() are mutually exclusive. Never initialize the same zmq_msg_t twice.

RETURN VALUE

The zmq_msg_init() function always returns zero.

ERRORS

No errors are defined.

EXAMPLE

Receiving a message from a socket.

zmq_msg_t msg;
rc = zmq_msg_init (&msg);
assert (rc == 0);
int nbytes = zmq_recv (socket, &msg, 0);
assert (nbytes != -1);
