// Warning messages
LM_STARTUP,
// Initialize the logger
LM_ERROR,
// Error messages
LM_CRITICAL,
// Critical conditions, such as hard device errors

// A condition that should be corrected immediately, such as a
// corrupted system database
LM_EMERGENCY,
// A panic condition. This is normally broadcast to all users

// In <ACE_Log_Priority>, LM_MAX is aliased to LM_EMERGENCY rather than
// being a distinct tag, but that is invalid IDL syntax. We
// adjust for this internally.
