  This logging library is not for the faint of heart. It's quite user-hostile, partly due to the lack of good documentation. Even so, this library can serve adequately for simple applications. The main problem lies with the way it manages lifetimes, memory and initialization. One cannot initialize the library more than once. If your client application forks, you better shut down the logger first, and then make sure that the new process immediately does an exec, after which the new process must reinitialize the logger. And the forking/parent process can no longer use the logger. This logger could be a great one with a few changes: 1. Get rid of all global/static objects. Allow the user to create and manage the DefaultContext, etc, with modern RAII techniques. 2. Allow the library to be initialized and uninitialized multiple times, similar to a Phoenix Singleton.

  Agree with kyberuserid..., I used this API in a project with hopes that it would simplify my task of development, but it didn't... Worked in native win32/x64 version of the application that uses it, but when called from managed code that uses the native version of application dll it throws scheduler_resource_allocation_error. So I'm going to consider looking for something else, maybe Pantheios - I'm back to square one after all that bloody hard work only to discover that I can't make a release because it fails with .NET
