Here is an example: [@#include <stdio.h> #include <string> class file_read_error { public: explicit file_read_error( std::string const & fn ): fn_(fn) { }; std::string const & file_name() const { return fn_; } private: std::string fn_; }; void file_read( FILE * f, void * buffer, size_t size ) { if( size!=fread(buffer,1,size,f) ) throw file_read_error("????"); }@] We have defined an exception class file_read_error which can store a file name, so that when we catch a file_read_error object, we know which file the failure is related to. However, the file_read function does not have the file name at the time of the throw; all it has is a FILE handle. One possible solution is to not use FILE handles directly. We could have our own class file which stores both a FILE handle and a file name, and pass that to file_read. However, this could be problematic if we communicate with 3rd party code that does not use our class file (probably because they have their own similar class.) A better solution is to make class file_read_error derive (possibly indirectly) from boost::(:link - 1 - - 0 - - -7 - - - 2 - :), and free the file_read function from the burden of storing the file name in exceptions it throws: [@#include <(:link - 1 - - 0 - - -32 - - - 2 - :)> #include <stdio.h> #include <errno.h> typedef boost::(:link - 1 - - 0 - - -6 - - - 2 - :)<struct tag_errno,int> errno_info; class file_read_error: public boost::(:link - 1 - - 0 - - -7 - - - 2 - :) { }; void file_read( FILE * f, void * buffer, size_t size ) { if( size!=fread(buffer,1,size,f) ) throw file_read_error() << errno_info(errno); }@] If file_read detects a failure, it throws an exception which contains the information that is available at the time, namely the errno. Other relevant information, such as the file name, can be added in a context higher up the call stack, where it is known naturally: [@#include <(:link - 1 - - 0 - - -32 - - - 2 - :)> #include <boost/shared_ptr.hpp> #include <stdio.h> #include <string> typedef boost::(:link - 1 - - 0 - - -6 - - - 2 - :)<struct tag_file_name,std::string> file_name_info; boost::shared_ptr<FILE> file_open( char const * file_name, char const * mode ); void file_read( FILE * f, void * buffer, size_t size ); void parse_file( char const * file_name ) { boost::shared_ptr<FILE> f = file_open(file_name,"rb"); assert(f); try { char buf[1024]; file_read( f.get(), buf, sizeof(buf) ); } catch( boost::(:link - 1 - - 0 - - -7 - - - 2 - :) & e ) { e << file_name_info(file_name); throw; } }@] The above function is (almost) exception-neutral -- if an exception is emitted by any function call within the try block, parse_file does not need to do any real work, but it intercepts any boost::(:link - 1 - - 0 - - -7 - - - 2 - :) object, stores the file name, and re-throws using a throw-expression with no operand (15.1.6).

Finally, (3) illustrates how the typedef from (1) can be used with (:link + 1 + + 0 + + -14 + + + 2 + |operator<<:) to store values in exception objects at the point of the throw. The stored errno value can be recovered at a later time like this: [@// ...continued void g() { try { f(); } catch( my_error & x ) { if( boost::shared_ptr<int const> err=boost::(:link + 1 + + 0 + + -10 + + + 2 + :)<errno_info>(x) ) std::cerr << "Error code: " << *err; } }@] The (:link + 1 + + 0 + + -10 + + + 2 + :) function template is instantiated with the typedef from (1), and is passed an exception object of a polymorphic type. If the exception object contains the requested value, the returned (:link http://www.boost.org/libs/smart_ptr/shared_ptr.htm|shared_ptr:) will point to it; otherwise an empty (:link http://www.boost.org/libs/smart_ptr/shared_ptr.htm|shared_ptr:) is returned. + + + + + 0 + + -16 + + + + 1 + 2 + (:auto !!:) !!!Synopsis (:include synopsis:) + + + + + 0 + + -17 + + + + 11 + 2 + (:auto !!!:) Here is how cloning can be enabled in a throw-expression (15.1): [@#include <(:link + 1 + + 0 + + -38 + + + 2 + :)> #include <stdio.h> #include <errno.h> typedef boost::error_info<struct tag_errno,int> errno_info; class file_read_error: public boost::(:link + 1 + + 0 + + -5 + + + 2 + :) { }; void file_read( FILE * f, void * buffer, size_t size ) { if( size!=fread(buffer,1,size,f) ) throw boost::(:link + 1 + + 0 + + -23 + + + 2 + :)(file_read_error()) << errno_info(errno); }@] Of course, (:link + 1 + + 0 + + -23 + + + 2 + :) may be used with any exception type; there is no requirement that it should derive from boost::(:link + 1 + + 0 + + -5 + + + 2 + :). + + + + + 0 + + -18 + + + + 37 + 2 + (:auto !!!:) When you catch an exception, you can call (:link + 1 + + 0 + + -22 + + + 2 + :) to get an (:link + 1 + + 0 + + -21 + + + 2 + :) object: [@#include <(:link + 1 + + 0 + + -11 + + + 2 + :)> #include <boost/thread.hpp> #include <boost/bind.hpp> void do_work(); //throws cloning-enabled boost::(:link + 1 + + 0 + + -5 + + + 2 + :)s void worker_thread( boost::(:link + 1 + + 0 + + -21 + + + 2 + :) & error ) { try { do_work(); error = boost::(:link + 1 + + 0 + + -21 + + + 2 + :)(); } catch( ... ) { error = boost::(:link + 1 + + 0 + + -22 + + + 2 + :)(); } }@] In the above example, note that (:link + 1 + + 0 + + -22 + + + 2 + :) captures the original type of the exception object.
