+ *  @class ACE_Stack_Trace
+ *
+ *  @brief Encapsulate a string representation of a stack trace on supported platforms.
+ *  Stack traces for code built with optimize=1 (or "Release" configs on Visual
+ *  Studio) may be misleading (missng frames) due to inlining performed by the
+ *  compiler, which is indepenent of the inline=0 / inline=1 build option and
+ *  the __ACE_INLINE__ / ACE_NO_INLINE macros.
+ *
+ *  A new conversion character, the question mark, was added to ACE_Log_Msg for stack
+ *  trace logging. The %? conversion character was added as a convenience so that users
+ *  need not instantiate an ACE_Stack_Trace instance solely for the  purpose of printing
+ *  it in an ACE logging message.  The following are functionally equivalent: 
+ *
+ *  \code
+ *     ACE_DEBUG((LM_DEBUG, "%?")); 
+ *
+ *     ACE_Stack_Trace st;
+ *     ACE_DEBUG ((LM_DEBUG, "%s", st.c_str() )); 
+ *  \endcode
+ *
+ *  These usage examples were shown in $ACE_ROOT/tests/Stack_Trace_Test.cpp.
+ *
+ *  @note The stack trace functionality was currently supported on platforms:
+ *        - Any platform using glibc as its runtime library, or where ACE_HAS_EXECINFO_H is defined 
+ *          (this covers Linux and Mac) and gcc version >= 3.3.
+ *        - VxWorks, both kernel and RTP
+ *        - Solaris
+ *        - Windows 32 and 64 bit (Visual C++, excluding WinCE/mobile)
+ *
+ *  @note Since stack trace buffer size has limitation(@c ACE_STACK_TRACE_SYMBUFSIZ), you will not 
+ *        get a complete stack trace if @c ACE_STACK_TRACE_SYMBUFSIZ value is less than actual stack 
+ *        trace data length. To get a complete stack trace, you need set @c ACE_STACK_TRACE_SYMBUFSIZ 
+ *        with a larger value that is enough for the stack trace data in your @c config.h file 
+ *        and rebuild ACE.
+ *
+ *  @note Using ACE logging mechanism (%?) to log the stack trace also has ACE_MAXLOGMSGLEN size limitation. 
+ *        To get a complete stack trace, you could use different output method. Following is an example.
+ *
+ *  \code
+ *        ACE_Stack_Trace st;
+ *        ACE_OS::printf("at [%s]\n", st.c_str());
+ *  \endcode
