Description

This is a fork of Denis Francesconi's PosixMQ-read node for Node-RED. Uses Mike Okner's posix-mq library.

This version allows the user to both write to a POSIX message queue and read from a POSIX message queue.

Requirements

• node.js -- tested against v8+

• node-red

• Linux 2.6.6+ or FreeBSD kernel with POSIX message queue support compiled in (CONFIG_POSIX_MQUEUE, which is enabled by default)

• See man mq_overview for how/where to modify global POSIX message queue resource limits

• Depends on nan & posix-mq which will be automatically installed when running npm install posixmq-read.

Values

These settings are applicable to both the posixmq-read and posixmq-write nodes.

• msgname - String - name of message queue.

• maxmsgs - Number - The maximum number of messages in the queue.

• msgsize - Number - The maximum size of messages in the queue.

• create - Boolean - Create the message queue if it is not already present.
