Build Status Coverage Status

A simple on-disk fixed length queue in the style of the Xen shared-memory-ring. In particular the producer and consumer APIs allow clients to control exactly when data is exposed to the consumer and removed from the queue.

Example usage

First create a "block device"-- any file will do:

dd if=/dev/zero of=test.raw bs=10240 count=1

Then initialise the ring in the file:

./main.native create

Then start two shells, in one run:

./main.native produce

and in the other

./main.native consume

The producer takes input from stdin and puts it onto the ring, and the consumer takes entries from the ring and prints them to stdout.

Build status

Results of building shared-block-ring with each compiler on check.ci.ocaml.org, run of against opam-repository 8a77e58. All results for this package.

Each result links to its build log. To keep crawlers from overloading the site, build logs require a GitHub sign-in (see ocurrent/opam-health-check). On your first log, GitHub asks you to “Authorize opam-health-check”, the OCurrent app that runs these checks; it sees only your public profile, not your repositories. The sign-in lasts 30 days.
