//
// The constant below defines how many (if any) messages will be reported
// to the event logger. As the number goes up in value more and more events
// will be reported. The purpose of this is to allow lots of messages during
// development and debugging (e.g. a message level of 3) to a minimum of
// messages (e.g. operational messages with a level of 1) or no messages if
// message logging inflicts too much of a performance penalty. Right now
// this is a compile time constant, but could later become a registry entry.
//
//    Levels:  LOG_NONE = No event log messages ever
//             LOG_USER = User event log messages (e.g. errors)
//             LOG_DEBUG = Minimum Debugging
//             LOG_VERBOSE = Maximum Debugging
//

#define  LOG_NONE     0
#define  LOG_USER     1
#define  LOG_DEBUG    2
#define  LOG_VERBOSE  3
#define  MESSAGE_LEVEL_DEFAULT  LOG_USER

// define macros
//
// Format for event log calls without corresponding insertion strings is:
//    REPORT_xxx (message_value, message_level)
//       where:
//          xxx is the severity to be displayed in the event log
//          message_value is the numeric ID from above
//          message_level is the "filtering" level of error reporting
//             using the error levels above.
//
// if the message has a corresponding insertion string whose symbol conforms
// to the format CONSTANT = numeric value and CONSTANT_S = string constant for
// that message, then the
//
//    REPORT_xxx_STRING (message_value, message_level)
//
// macro may be used.
//
//
// REPORT_SUCCESS was intended to show Success in the error log, rather it
// shows "N/A" so for now it's the same as information, though it could
// (should) be changed  in the future
//
