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 referenced 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.
Otherwise it shall return -1 and set errno to one of the values defined
below.
ERRORS
ENOMEM
Insufficient storage space is available.
