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 initialize 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.
