Pantheios 1.0.1 Beta 31

Pantheios is an Open Source C/C++ Logging API library, offering an optimal combination of 100% type-safety, efficiency, genericity and extensibility. It is simple to use and extend, highly-portable (platform and compiler-independent) and, best of all, it upholds the C tradition of you only pay for what you use.
The project supports logging of message statements of arbitrary complexity, consisting of heterogenous types.
Pantheios supports filtering of log messages based on severity level including (but not limited to) the eight levels defined by the SysLog protocol.
Pantheios supports back-end output, individually and in combination, to stderr/stdout, SysLog (including a custom implementation of the SysLog protocol for Windows), Win32 debugger, Win32 event log, COM Error Object, or any custom back-end extension you care to write. Importantly, Pantheios is readily extended to use the existing transport mechanisms of feature-rich logging libraries such as ACE, log4cpp, log4cplus, log4cxx.
Pantheios does not contain any compiler-specific or platform-specific constructs. It supports UNIX (including Linux and Mac OS-X), and Windows, and should work with any operating system. It is known to be compatible with Borland (5.5.1+), Comeau (4.3.3+), Digital Mars (8.45+), GCC (3.2+), Intel (6+), Metrowerks (8+), Microsoft Visual C++ (5.0+), and should work with any reasonably modern C++ compiler.
Pantheios is completely free and includes source released under a BSD-style licence.
Pantheios was forked from a previous logging architecture, proprietary to Synesis Software, in 2005, and has been used in a number of commercial projects since that time. In one project it serves a middleware suite that handles 10s of millions of financial transactions per week, wherein it has an unmeasurably low impact on performance when logging (of a given severity level) is switched off. (Its also decidedly quick with logging switched on, of course ...).
Enhancements:
- A bug in the Pantheios Tracing API was fixed.
- An example for the Pantheios Tracing API was added.
- A variadic macro warning in GCC 3.x makefiles was suppressed.
