## Enumeration Type Documentation

enum ACE_Log_Priority

This data type indicates the relative priorities of the logging messages, from lowest to highest priority.

These values are defined using powers of two so that it's possible to form a mask to turn them on or off dynamically. We only use 12 bits, however, so users are free to use the remaining 19 bits to define their own priority masks.

Enumeration values:

  LM_SHUTDOWN | Shutdown the logger (decimal 1).
  LM_TRACE | Messages indicating function-calling sequence (decimal 2).
  LM_DEBUG | Messages that contain information normally of use only when debugging a program (decimal 4).
  LM_INFO | Informational messages (decimal 8).
  LM_NOTICE | Conditions that are not error conditions, but that may require special handling (decimal 16).
  LM_WARNING | Warning messages (decimal 32).
  LM_STARTUP | Initialize the logger (decimal 64).
  LM_ERROR | Error messages (decimal 128).
  LM_CRITICAL | Critical conditions, such as hard device errors (decimal 256).
  LM_ALERT | A condition that should be corrected immediately, such as a corrupted system database (decimal 512).
  LM_EMERGENCY | A panic condition. This is normally broadcast to all users (decimal 1024).
  LM_MAX | The maximum logging priority.
  LM_ENSURE_32_BITS | Do not use!! This enum value ensures that the underlying integral type for this enum is at least 32 bits.
