Name

Zmq_msg_init_size-initializes the ZMQ Message Object with a specified space size

Synopsis

int zmq_msg_init_size (zmq_msg_t *msg, size_t size);

Description

The zmq_msg_init_size () function allocates any requested resource to store a size byte message, and initializes The message specified by the MSG parameter. Used to represent the newly assigned message.

When the function executes, it will choose whether to store the message in the stack (small message) or in the heap (Big message). For performance reasons, thezmq_msg_init_size () function does not clear the message data.

You should never directly manipulate the zmq_msg_t object directly, but instead use the zmq_msg function family to do so.

The three functions of Zmq_msg_init (),zmq_msg_init_data () , and zmq_msg_init_size () are mutually exclusive. Never initialize a zmq_msg_t object two of times.

Return value

function zmq_msg_init_size () returns 0 when execution succeeds . Otherwise , 1is returned, and the value of errno is set to the value defined below.

Errors
