{
// = TITLE
// This class is used to instrument code. This is accomplished
// by inserting time probes at different location in the code.
// ACE_Timeprobe then measures the time difference between two
// time probes.
//
// = DESCRIPTION
// This class provides a lightweight implementation for
// measuring the time required to execute code between two time
// probes. When a time probe executes, it records the time, the
// id of the calling thread, and an event description. The
// event description can either be an unsigned long or a string
// (char *). If string are used, care must be taken cause only
// pointer copies are done and the string data is *not* copied.
//
// The recorded time probes can then be printed by calling
// print_times(). If you have used unsigned longs as event
// descriptions in any of your time probes, you must have
// provided an event description table that maps the unsigned
// longs to readable strings. This map is a simple array of
// strings, and the event number is used as the index into the
// array when looking for the event description. If you have
// only used strings for the event description, this map is not
// necessary.
//
// Multiple maps can also be used to chunk up the time probes.
// Each one can be added by calling event_descriptions().
// Different tables are used internally by consulting the
// minimum_id for each table. It is up to the user to make sure
// that multiple tables do not share the same event id range.
