----------------------------------------+-----------------------------------
 I was attempting to learn how to extract the file, function, & line number
 from a caught exception for logging and noticed the following in
 boost_throw_exception_test found in throw_exception_test.cpp:


 {{{
 char const * const * file=boost::get_error_info<boost::throw_function>(x);
 char const * const * function=boost::get_error_info<boost::throw_file>(x);
 }}}


 It appears the file is retrieving the function name and vice versa.  I
 didn't check to see if there were other instances of this occurrance.

 I'm novice so I may be very wrong.
 FYI: I was in this area because I couldn't figure out from the
 documentation how to access the values placed by BOOST_THROW_EXCEPTION.  I
 finally figured out the following based upon what I found in your test
 file:

 {{{
 if( char const * const * file=boost::get_error_info<boost::throw_file>(e)
 ) cout << "The File where it happened:" << *file << "\n";
 if( char const * const *
 function=boost::get_error_info<boost::throw_function>(e) ) cout << "The
 Function where it happened:" << *function << "\n";
 if( int const * line=boost::get_error_info<boost::throw_line>(e) ) cout <<
 "The Line where it happened:" << *line << "\n";
 }}}
