What is libslack?

Libslack is a library of general utilities designed to make UNIX/C programming a bit easier on the eye. It is a seemingly random collection of modules and functions that I find commonly useful. It was originally implemented as part of the daemon program (although some of the code dates back much further).

It's a small library with lots of functionality, accurately documented and thoroughly tested. Good library naming conventions are not rigorously observed on the principle that common operations should always be easy to write and code should always be easy to read.

Libslack is freely available under the GNU General Public License.

Features

For more information read the manual entries in the Documentation section.

Supported Platforms

Currently, libslack is only known to compile and work on:

It is written in ISO C using POSIX almost exclusively except for some BSD functions that appear on most systems (e.g. sockets). So it shouldn't be difficult to get it working on other (recent) systems that support ISO C, POSIX and XPG4.

Documentation

There is a README file, libslack overview manpage, a manpage for each module in libslack and a manpage for the libslack-config utility. There is also the paper MT-Disciplined - decoupling thread safety.

Mailing Lists

If you'd like to be kept up to date with libslack releases or have questions or suggestions, you can join one or more of the following mailing lists (@libslack.org).

  slack-announce (Announcements)
slack-users (User forum)
slack-dev (Development forum)

To subscribe to any of these mailing lists, send a mail message to listname-request@libslack.org with subscribe as the message body.

 
$ echo subscribe | mail slack-announce-request@libslack.org
$ echo subscribe | mail slack-users-request@libslack.org
$ echo subscribe | mail slack-dev-request@libslack.org

Or you can send a mail message to majordomo@libslack.org with subscribe listname in the message body. This way, you can include multiple subscribe commands to subscribe to multiple lists at the same time.

 
$ mail majordomo@libslack.org
subscribe slack-announce
subscribe slack-users
subscribe slack-dev
.

A digest version of each mailing list is also available. Subscribe to digests as above but append -digest to the listname.

 
$ echo subscribe | mail slack-announce-digest-request@libslack.org
$ echo subscribe | mail slack-users-digest-request@libslack.org
$ echo subscribe | mail slack-dev-digest-request@libslack.org

Or

 
$ mail majordomo@libslack.org
subscribe slack-announce-digest
subscribe slack-users-digest
subscribe slack-dev-digest
.

Note that these are all extremely low volume mailing lists so there's not much use for the digest lists.
