NAME

       zmq_msg_init_size - initialise 0MQ message of a specified size

SYNOPSIS

       int zmq_msg_init_size (zmq_msg_t *msg, size_t size);

DESCRIPTION

       The zmq_msg_init_size() function shall allocate any resources required to store a message
       size bytes long and initialise the message object referenced by msg to represent the newly
       allocated message.

       The implementation shall choose whether to store message content on the stack (small
       messages) or on the heap (large messages). For performance reasons zmq_msg_init_size()
       shall not clear the message data.

           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 initialise the same zmq_msg_t twice.

RETURN VALUE

       The zmq_msg_init_size() function shall return zero if successful. Otherwise it shall
       return -1 and set errno to one of the values defined below.

ERRORS

       ENOMEM
           Insufficient storage space is available.
