Pantheios

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. Pantheios 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 file, stderr/stdout, SysLog (including a custom implementation of the SysLog protocol for Windows), Windows debugger, Windows event log, COM Error Object, speech, 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.
