libmsgque is a connectivity toolkit with the main goal to serve as bridge between an API and a programming toolkit


near all application toolkits offering an API to give the user a chance to integrate the application toolkit into the local environment. example:

programming toolkit

a programming toolkit serve as an interface between the human and the computer. The human create input, knows as source-code, to instruct the computer to do complex work. example:


libmsgque acts as a bridge between a programming toolkit and an API:

  <<<<<<<<<<<<<<<< ANSWER <<<<<<<<<<<<<<

A REQUEST will be submitted with libmsgque from the programming toolkit to the API and the ANSWER will be send back. the advantage of libmsgque is:

  1. the programming toolkit and the API were separated into independent processes
  2. the interface between the API and libmsgque is independent from the interface between the programming toolkit and libmsgque
  3. the interface between the programming toolkit and libmsgque is only written with the programming toolkit language (example: Tcl, no C knowledge required)

MAKR (2009-11-12) notes that this package is available under GPL v2 (not LGPL).

Andreas Otto (2009-11-12) the only reason is that autoreconf -f -v -i create the file COPYING (GPL v2) in the top-level directory and nobody complain about this until now

MAKR (2009-11-27) resurrected the page, as this actually has relevance to Tcl. I wasn't complaining about all of your stuff, Andreas, just the few things that so far were only ideas.

With regard to the license: this is also not a complaint. But as it stands, the package is available under GPL, which might be unexpected for the casual library user. As the owner of the package you may of course license it under what-ever license you think is appropriate...

Andreas Otto (2009-11-27) I understand what you want to say, now my answer ... The problem is that I, as you mentioned, work on different areas. Some belonging closer to Tcl and some not. I don't want to setup/use for every single task a different Wiki. This mean I looking for a One Wiki Fits All solution. The reason why I move the pages to an other place is that I update only this other place and to have a single up-tp-date place for one single project is better as to have multiple places with mostly non up-tp-date information. -> libmsgque (3.8) is the last release, In future libmsgque will be part of the NHI1 project and updates/fixes will be only done to the NHI1 project tree.
