ZMQ_MSG_INIT_BUFFER(3) 0MQ Manual ZMQ_MSG_INIT_BUFFER(3) NAME zmq_msg_init_buffer - initialise 0MQ message with buffer copy SYNOPSIS int zmq_msg_init_buffer (zmq_msg_t *msg, const void *buf, size_t size); DESCRIPTION The zmq_msg_init_buffer() function shall allocate any resources required to store a message size bytes long and initialise the message object refer- enced by msg to represent a copy of the buffer referenced by the buf and size arguments. The implementation shall choose whether to store message content on the stack (small messages) or on the heap (large messages). 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(), zmq_msg_init_buffer() and zmq_msg_init_buffer() are mutually exclusive. Never initialise the same zmq_msg_t twice. RETURN VALUE The zmq_msg_init_buffer() function shall return zero if successful. Other- wise it shall return -1 and set errno to one of the values defined below. ERRORS ENOMEM Insufficient storage space is available.
