/**
* @file Timeprobe.h
*
* $Id$
*
* @author Irfan Pyarali
*
* If users want to use time probes, the ACE_COMPILE_TIMEPROBES
* flag must be defined when compiling ACE. This can be achieved
* by doing one of the following:
*
* . Use make probe = 1, if you are using the make utility.
*
* . Define ACE_COMPILE_TIMEPROBES in config.h
*
* . Define ACE_COMPILE_TIMEPROBES in the VC project file.
*
* . Other regular methods will also work.
*
* It is not necessary to define ACE_COMPILE_TIMEPROBES when using
* time probes, you simply need ACE_ENABLE_TIMEPROBES. You can use
* the ACE_TIMEPROBE_* macros to program the time probes, and use
* the ACE_ENABLE_TIMEPROBE to enable the time probes. If you
* define ACE_ENABLE_TIMEPROBE in your code, but forget to compile
* ACE with ACE_COMPILE_TIMEPROBES, you will end up with linker
* errors.
*
* Remember that ACE_COMPILE_TIMEPROBES means that the ACE library
* will contain code for time probes. This is only useful when
* compiling ACE. ACE_ENABLE_TIMEPROBES means that the
* ACE_TIMEPROBE_* macros should spring to life.
