zmq_msg_init \- initialise empty 0MQ message
34
\fBint zmq_msg_init (zmq_msg_t \fR\fB\fI*msg\fR\fR\fB);\fR
37
The \fIzmq_msg_init()\fR function shall initialise the message object referenced by \fImsg\fR to represent an empty message\&. This function is most useful when called before receiving a message with \fIzmq_recv()\fR\&.
43
.nr an-no-space-flag 1
51
Never access \fIzmq_msg_t\fR members directly, instead always use the \fIzmq_msg\fR family of functions\&.
59
.nr an-no-space-flag 1
67
The functions \fIzmq_msg_init()\fR, \fIzmq_msg_init_data()\fR and \fIzmq_msg_init_size()\fR are mutually exclusive\&. Never initialize the same \fIzmq_msg_t\fR twice\&.
72
The \fIzmq_msg_init()\fR function shall return zero if successful\&. Otherwise it shall return \-1 and set \fIerrno\fR to one of the values defined below\&.
75
No errors are defined\&.
78
\fBReceiving a message from a socket\fR.
85
rc = zmq_msg_init (&msg);
87
rc = zmq_recv (socket, &msg, 0);
