Pantheios - The C++ Logging Sweetspot

• Atomicity - all parts of a statement are emitted (or not) to the back-end transports in a single action.
• Efficiency - the length of each element in a statement is determined at most once; the contents of each element in a statement is copied at most once; memory is allocated for the prepared statement at most once (and even then only if the total statement length exceeds 2047 characters).
• Extensibility - the back-end transport can be customised by the user to any conceivable transport, should the stock back-ends prove insufficient for a particular need. The distribution includes transports over the following:
  • SysLog
  - both UNIX and Windows
  • COM Error Object
  • Adaptive Communications Environment (ACE) Logger
  • Windows Debugger
  • Windows Event Log
  • stdout/stderr
• Filtered - statements are filtered based on a 32-bit severity level, incorporating, but not limited to, the standard eight levels described by SysLog
• Genericity - log statement elements may be of arbitrary type. Support for a large number of known types is implicit because Pantheios uses the STLSoft libraries. Extension to new/custom types is achievable by several different techniques, which one selects as appropriate.
• 100% type-safety - Use of Pantheios from C++ is 100% type-safe (unlike the unsafe printf()-family, or the IOStreams).

• You don't pay for what you don't use. If a statement at a given severity level is not to be emitted, no conversions, no concatenations, no memory allocation nor any other expensive operations are carried out.

The library is compatible with a large range of C++ compilers. It even compiles with Visual C++ v5.0!
