NAME

|
----
|
|
zmq_msg_init - initialise empty 0MQ message
|
|
|
|
|
|
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 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.
