zmq_msg_init_size \- initialise 0MQ message of a specified size
34
\fBint zmq_msg_init_size (zmq_msg_t \fR\fB\fI*msg\fR\fR\fB, size_t \fR\fB\fIsize\fR\fR\fB);\fR
37
The \fIzmq_msg_init_size()\fR function shall allocate any resources required to store a message \fIsize\fR bytes long and initialise the message object referenced by \fImsg\fR to represent the newly allocated message\&.
39
The implementation shall choose whether to store message content on the stack (small messages) or on the heap (large messages)\&. For performance reasons \fIzmq_msg_init_size()\fR shall not clear the message data\&.
45
.nr an-no-space-flag 1
53
Never access \fIzmq_msg_t\fR members directly, instead always use the \fIzmq_msg\fR family of functions\&.
61
.nr an-no-space-flag 1
69
The functions \fIzmq_msg_init()\fR, \fIzmq_msg_init_data()\fR and \fIzmq_msg_init_size()\fR are mutually exclusive\&. Never initialize the same \fIzmq_msg_t\fR twice\&.
74
The \fIzmq_msg_init_size()\fR function shall return zero if successful\&. Otherwise it shall return \-1 and set \fIerrno\fR to one of the values defined below\&.
79
Insufficient storage space is available\&.
