<h2 id="_description">DESCRIPTION</h2>
<div class="sectionbody">
<div class="paragraph"><p>The <em>zmq_msg_init_size()</em> function shall allocate any resources required to
store a message <em>size</em> bytes long and initialise the message object referenced
by <em>msg</em> to represent the newly allocated message.</p></div>
<div class="paragraph"><p>The implementation shall choose whether to store message content on the stack
(small messages) or on the heap (large messages). For performance reasons
<em>zmq_msg_init_size()</em> shall not clear the message data.</p></div>
