ZMQ_MSG_INIT_SIZE(3) 0MQ Manual ZMQ_MSG_INIT_SIZE(3)
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(),
zmq_msg_init_size() and zmq_msg_init_buffer() 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.
