The Log Writer Library (LWL) is a collection of routines for writing logs messages to files from C programms. It is a portable and re-entrant library fully written from scratch in pure ANSI C. It is designed to offer for C programmers common routines for logging messages in a highly customisable way.
The current version is LWL-1.1.0. It was released on January 11, 2005.
You can download it from http://download.gna.org/lwl/.

The LWL Reference Manual is available online, in following formats:
We require that LWL should build on any system with an ANSI C compiler, so if doesn't, that's a bug and we would love a patch!
You can also check out the very latest version via anonymous cvs. Here's how:
cvs -d:pserver:firstname.lastname@example.org:/cvs/lwl co lwlOnce you have it checked out, you can update it with cvs update.
You can also view the cvs archive via cvsweb.
Note: if you use anonymous CVS, you will need some GNU tools that usually only developers use, and which are not required to build GNU packages from tarballs. These are automake, autoconf, libtool, GNU m4, GNU make, and others which might escape me now. They all come with recent GNU/Linux distributions, and for other OSes they can be found at ftp://ftp.gnu.org/pub/gnu/
To begin the build process from a CVS checkout, start with:
./autogen.shwhich will prepare the package for compilation. You can then use
makein the usual way.
