6 zmq_msg_init_size - initialise 0MQ message of a specified size
7
9 int zmq_msg_init_size (zmq_msg_t *msg, size_t size);
10
12 The zmq_msg_init_size() function shall allocate any resources required
13 to store a message size bytes long and initialise the message object
14 referenced by msg to represent the newly allocated message.
15
16 The implementation shall choose whether to store message content on the
17 stack (small messages) or on the heap (large messages). For performance
18 reasons zmq_msg_init_size() shall not clear the message data.
19
20 Caution
21 Never access zmq_msg_t members directly, instead always use the
22 zmq_msg family of functions.
23
24 Caution
25 The functions zmq_msg_init(), zmq_msg_init_data(),
26 zmq_msg_init_size() and zmq_msg_init_buffer() are mutually
27 exclusive. Never initialise the same zmq_msg_t twice.
28
30 The zmq_msg_init_size() function shall return zero if successful.
31 Otherwise it shall return -1 and set errno to one of the values defined
32 below.
33
35 ENOMEM
36 Insufficient storage space is available.
