http://www.ossp.org/pkg/lib/l2/ Flexible Logging Abstract OSSP l2 is a C library providing a very flexible and sophisticated Unix logging facility. It is based on the model of arbitrary number of channels, stacked together in a top-down data flow tree structure with filtering channels in internal nodes and output channels on the leave nodes. Channel trees can be either constructed manually through lower-level API functions or all at once with a single API function controlled by a compact syntactical description of the channel tree. For generating log messages a printf-style formatting engine is provided which can be extended through callback functions. The data flow inside the channel tree is controlled by (eight fixed and nine custom) logging message severity levels which are assigned to each individual channel. Channels are implemented by channel handlers which can be even customer supplied for creating own channels which seamlessly integrate into the framework. For convinience reasons, OSSP l2 already ships with pre-implemented filtering (noop, filter, prefix, buffer) and output (null, fd, file, pipe, socket, syslog, smtp) channels which already cover mostly all use cases of logging. -- Alexandre Dulaunoy -- http://www.foo.be/ 3B12 DCC2 82FA 2931 2F5B 709A 09E2 CD49 44E6 CBCD --- AD993-6BONE "People who fight may lose.People who do not fight have already lost."
