When exceptions derive from boost::(:link 1 0 -35 2 :), arbitrary data can be added to exception objects: *At the point of the throw; *At a later time as exceptions bubble up the call stack.

The T sub-object is initialized from x by the T copy constructor. !!!!Throws: Nothing. 0 -9 17 2 (:auto !!!:) (:include synopsis:) The (:link 1 0 -9 2 :) type can be used to refer to a copy of an exception object. It is Default Constructible, Copy Constructible, Assignable and Equality Comparable; (:link 1 0 -9 2 :)'s operations do not throw. Two instances of (:link 1 0 -9 2 :) are equivalent and compare equal if and only if they refer to the same exception. The default constructor of (:link 1 0 -9 2 :) produces the null value of the type. The null value is equivalent only to itself. !!!!Thread safety * It is legal for multiple threads to hold (:link 1 0 -9 2 :) references to the same exception object. * It is illegal for multiple threads to modify the same (:link 1 0 -9 2 :) object concurrently. * While calling (:link 1 0 -22 2 :) makes a copy of the current exception object, it is still possible for the two copies to share internal state. Therefore, in general it is not safe to call (:link 1 0 -33 2 :) concurrently to throw the same exception object into multiple threads. 0 -10 57 2 (:auto !!!:) !!!Why use operator<< overload for adding info to exceptions? Before throwing an object of type that derives from boost::(:link 1 0 -35 2 :), it is often desirable to add one or more (:link 1 0 -36 2 :) objects in it. The syntactic sugar provided by (:link 1 0 -7 2 :) allows this to be done directly in a throw expression: [@throw error() (:link 1 0 -7 2 |<<:) foo_info(foo) (:link 1 0 -7 2 |<<:) bar_info(bar);@] which saves typing compared to this possible alternative: [@error e; e.add(foo_info(foo)); e.add(bar_info(bar)); throw e;@] and looks better than something like: [@throw error().add(foo_info(foo)).add(bar_info(bar));@] !!!Why is boost::exception abstract? To prevent exception-neutral contexts from erroneously erasing the type of the original exception when adding (:link 1 0 -36 2 :) to an active exception object: [@catch( boost::(:link 1 0 -35 2 :) & e ) { e (:link 1 0 -7 2 |<<:) foo_info(foo); throw e; //Compile error: boost::(:link 1 0 -35 2 :) is abstract }@] The correct code is: [@catch( boost::(:link 1 0 -35 2 :) & e ) { e (:link 1 0 -7 2 |<<:) foo_info(foo); throw; //Okay, re-throwing the original exception object. }@] !!!Why doesn't boost::exception derive from std::exception? Despite that (:link 1 0 -34 2 |virtual inheritance should be used in deriving from base exception types:), many programmers fail to follow this principle when deriving from std::exception. If boost::(:link 1 0 -35 2 :) derives from std::exception, using the 1 0 -8 2 function with such user-defined types would introduce dangerous ambiguity which would break all catch(std::exception &) statements. Of course, boost::(:link 1 0 -35 2 :) should not be used to replace std::exception as a base type in exception type hierarchies. Instead, it should be included as a virtual base, in addition to std::exception (which should also be derived virtually.) !!!What is the space overhead of the boost::exception base class? The space overhead for the boost::exception data members is negligible in the context of exception handling. Throwing objects that derive from boost::(:link 1 0 -35 2 :) does not by itself cause dynamic memory allocations. Deriving from boost::(:link 1 0 -35 2 :) enables any data to be added to exceptions, which usually does allocate memory. However, this memory is reclaimed when the exception has been handled, and since typically user code does not allocate memory during the unrolling of the stack, adding error info to exceptions should not cause memory fragmentation. !!!Why is boost::exception integrated in boost::throw_exception? The boost::(:link 1 0 -32 2 :) function predates the Boost Exception library and there has been some concern about its current behavior of injecting boost::(:link 1 0 -35 2 :) as a base of any exception passed to boost::(:link 1 0 -32 2 :). Such concerns are dictated by the typical strict interpretation of a common principle in C and C++, that users only pay for features they actually use. The problem is that users of Boost Exception can't by themselves cause a library to throw types that derive from boost::(:link 1 0 -35 2 :), and without this they can't use any of the Boost Exception facilities. For example, if a user wants to use Boost Serialization in a separate thread, it is desirable to be able to transport exceptions emitted by that library into the main thread where they can be analyzed to generate a user-friendly message. This can be easily achieved using boost::(:link 1 0 -9 2 :), but this requires that Boost Serialization throws exceptions using boost::(:link 1 0 -17 2 :). If Boost Serialization calls boost::(:link 1 0 -32 2 :) to throw, this behavior happens automatically and transparently. The cost of this integration is: * In terms of space: a pointer and 3 ints are added to the static size of exception objects. * In terms of speed: the pointer is initialized to null at the point of the throw. * In terms of coupling: about 400 self-contained lines of C++ with no external includes. !!!Should I call boost::throw_exception or BOOST_THROW_EXCEPTION? It is preferable to throw exceptions using the (:link 1 0 -18 2 :) macro. This has the benefit of recording in the exception object the __FILE__ and __LINE__ of the throw, as well as the pretty name of the function that throws. This has virtually no overhead, yet enables boost::(:link 1 0 -21 2 :) to compose a more useful, if not user-friendly message. Typical use of boost::(:link 1 0 -21 2 :) is: [@catch( boost::exception & e ) { std::cerr << "OMG!" << boost::diagnostic_information(e); } catch( ... ) { std::cerr << "OMG!!!"; }@] This is a possible message it may display, the first line is only possible if (:link 1 0 -18 2 :) is used: [@example_io.cpp(83): Throw in function void parse_file(const char *) Dynamic exception type: class file_open_error std::exception::what: example_io error [struct tag_errno_code *] = 2, OS says "No such file or directory" [struct tag_file_name *] = tmp1.xml [struct tag_function *] = fopen [struct tag_open_mode *] = rb@] 0 -11 7 2 (:auto !!!:) Deriving from boost::(:link 1 0 -35 2 :) effectively decouples the semantics of a failure from the information that is relevant to each individual instance of reporting a failure with a given semantic. In other words: with boost::(:link 1 0 -35 2 :), what data a given exception object transports depends primarily on the context in which failures are reported (not on its type.) Since exception types need no members, it becomes very natural to throw exceptions that derive from more than one type to indicate multiple appropriate semantics: [@struct exception_base: virtual std::exception, virtual boost::(:link 1 0 -35 2 :) { }; struct io_error: virtual exception_base { }; struct file_error: virtual io_error { }; struct read_error: virtual io_error { }; struct file_read_error: virtual file_error, virtual read_error { };@] Using this approach, exception types become a simple tagging system for categorizing errors and selecting failures in exception handlers. 0 -12 27 2 (:auto !!:) Some exception hierarchies can not be modified to make boost::(:link 1 0 -35 2 :) a base type. In this case, the (:link 1 0 -8 2 :) function template can be used to make exception objects derive from boost::(:link 1 0 -35 2 :) anyway. Here is an example: [@#include <(:link 1 0 -49 2 :)> #include <stdexcept> typedef boost::(:link 1 0 -36 2 :)<struct tag_std_range_min,size_t> std_range_min; typedef boost::(:link 1 0 -36 2 :)<struct tag_std_range_max,size_t> std_range_max; typedef boost::(:link 1 0 -36 2 :)<struct tag_std_range_index,size_t> std_range_index; template <class T> class my_container { public: size_t size() const; T const & operator[]( size_t i ) const { if( i > size() ) throw boost::(:link 1 0 -8 2 :)(std::range_error("Index out of range")) << std_range_min(0) << std_range_max(size()) << std_range_index(i); //.... } }; @] The call to (:link 1 0 -8 2 :)<T> gets us an object of ''unspecified type'' which is guaranteed to derive from both boost::(:link 1 0 -35 2 :) and T. This makes it possible to use (:link 1 0 -7 2 mod="/":) to store additional information in the exception object. The exception can be intercepted as T &, so existing exception handling will not break. It can also be intercepted as boost::(:link 1 0 -35 2 :) &, so that (:link 1 0 -5 2 |more information can be added to the exception at a later time:). 0 -13 37 2 (:auto !!!:) When you catch an exception, you can call (:link 1 0 -22 2 :) to get an (:link 1 0 -9 2 :) object: [@#include <(:link 1 0 -56 2 :)> #include <boost/thread.hpp> #include <boost/bind.hpp> void do_work(); //throws cloning-enabled boost::(:link 1 0 -35 2 :)s void worker_thread( boost::(:link 1 0 -9 2 :) & error ) { try { do_work(); error = boost::(:link 1 0 -9 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. The exception can be thrown again using the (:link 1 0 -33 2 :) function: [@// ...continued void work() { boost::(:link 1 0 -9 2 :) error; boost::(:link http://www.boost.org/doc/html/boost/thread.html|thread:) t( boost::(:link http://www.boost.org/libs/bind/bind.html|bind:)(worker_thread,boost::(:link http://www.boost.org/doc/html/ref.html|ref:)(error)) ); t.(:link http://www.boost.org/doc/html/boost/thread.html|join:)(); if( error ) boost::(:link 1 0 -33 2 :)(error); }@] Note that (:link 1 0 -22 2 :) could fail to copy the original exception object in the following cases: * if there is not enough memory, in which case the returned (:link 1 0 -9 2 :) points to an instance of std::bad_alloc, or * if (:link 1 0 -17 2 :) was not used in the throw-expression passed to the original throw statement and the current implementation does not have the necessary compiler-specific support to copy the exception automatically, in which case the returned (:link 1 0 -9 2 :) points to an instance of (:link 1 0 -28 2 :). Regardless, the use of (:link 1 0 -22 2 :) and (:link 1 0 -33 2 :) in the above examples is well-formed. 0 -14 5 2 (:auto !!!:) (:include synopsis:) !!!!Effects: As if [@try { throw 1 0 -17 2 (e); } catch(...) { return (:link 1 0 -22 2 :)(); }@] 0 -15 5 2 (:auto !!!:) (:include synopsis:) !!!!Requirements: E must be boost::(:link 1 0 -35 2 :), or a type that derives (indirectly) from boost::(:link 1 0 -35 2 :). !!!!Effects: Equivalent to x << v.(:link http://www.boost.org/libs/tuple/doc/tuple_users_guide.html#accessing_elements|get:)<0>() << ... << v.(:link http://www.boost.org/libs/tuple/doc/tuple_users_guide.html#accessing_elements|get:)<N>(). !!!!Returns: x.

If the second macro is also defined, Boost Exception does not use static typeid either. There are no observable degrading effects on the library functionality, except for the following: ->By default, the (:link 1 0 -29 2 :) function template can be called with any exception type. If BOOST_NO_RTTI is defined, (:link 1 0 -29 2 :) can be used only with objects of type boost::(:link 1 0 -35 2 :). !!!!Note: The library needs RTTI functionality.

'''BOOST_EXCEPTION_DISABLE''' By default, (:link 1 0 -17 2 :) and (:link 1 0 -8 2 :) are integrated directly in the (:link 1 0 -32 2 :) function. Defining BOOST_EXCEPTION_DISABLE disables this integration. Note that on some non-conformant compilers, for example MSVC 7.0 and older, as well as BCC, BOOST_EXCEPTION_DISABLE is implicitly defined in (:link 1 0 -57 2 :). 0 -17 21 2 (:auto !!!:) (:include synopsis:) !!!!Requirements: T must be a class with an accessible no-throw copy constructor. !!!!Returns: An object of ''unspecified'' type which derives publicly from T.

See (:link 1 0 -22 2 :) for details. !!!!Note: Instead of using the throw keyword directly, it is preferable to call boost::(:link 1 0 -32 2 :). This is guaranteed to throw an exception that derives from boost::(:link 1 0 -35 2 :) and supports the (:link 1 0 -9 2 :) functionality. 0 -18 7 2 (:auto !!!:) (:include synopsis:) This macro takes an exception object, records BOOST_CURRENT_FUNCTION, __FILE__ and __LINE__ in it, and forwards it to 1 0 -32 2 . To recover this information at the catch site, use 1 0 -29 2 ; the information is also included in the message returned by 1 0 -21 2 . 0 -19 33 2 (:auto !!!:) Traditionally, when using exceptions to report failures, the throw site: *creates an exception object of the appropriate type, and *stuffs it with data relevant to the detected error. A higher context in the program contains a catch statement which: *selects failures based on exception types, and *inspects exception objects for data required to deal with the problem. The main issue with this "traditional" approach is that often, the data available at the point of the throw is insufficient for the catch site to handle the failure. Here is an example of a catch statement: [@catch( file_read_error & e ) { std::cerr << e.file_name(); }@] And here is a possible matching throw: [@void read_file( FILE * f ) { .... size_t nr=fread(buf,1,count,f); if( ferror(f) ) throw file_read_error(???); .... }@] Clearly, the problem is that the handler requires a file name but the read_file function does not have a file name to put in the exception object; all it has is a FILE pointer! In an attempt to deal with this problem, we could modify read_file to accept a file name: [@void read_file( FILE * f, char const * name ) { .... size_t nr=fread(buf,1,count,f); if( ferror(f) ) throw file_read_error(name); .... }@] This is not a real solution: it simply shifts the burden of supplying a file name to the immediate caller of the read_file function. ->''In general, the data required to handle a given library-emitted exception depends on the program that links to it. Many contexts between the throw and the catch may have relevant information which must be transported to the exception handler.'' !!!Exception wrapping The idea of exception wrapping is to catch an exception from a lower level function (such as the read_file function above), and throw a new exception object that contains the original exception (and also carries a file name.) This method seems to be particularly popular with C++ programmers with Java background. Exception wrapping leads to the following problems: *To wrap an exception object it must be copied, which may result in slicing. *Wrapping is practically impossible to use in generic contexts. The second point is actually special case of violating the exception neutrality principle. Most contexts in a program can not handle exceptions; such contexts should not interfere with the process of exception handling. !!!The boost::exception solution *Simply derive your exception types from boost::(:link 1 0 -35 2 :). *Confidently limit the throw site to provide only data that is available naturally. *Use exception-neutral contexts between the throw and the catch to augment exceptions with more relevant data as they bubble up. For example, in the throw statement below we only add the errno code, since this is the only failure-relevant information available in this context: [@struct exception_base: virtual std::exception, virtual boost::(:link 1 0 -35 2 :) { }; struct io_error: virtual exception_base { }; struct file_read_error: virtual io_error { }; typedef boost::(:link 1 0 -36 2 :)<struct tag_errno_code,int> errno_code; void read_file( FILE * f ) { .... size_t nr=fread(buf,1,count,f); if( ferror(f) ) throw file_read_error() (:link 1 0 -7 2 |<<:) errno_code(errno); .... }@] In a higher exception-neutral context, we add the file name to ''any'' exception that derives from boost::(:link 1 0 -35 2 :): [@typedef boost::(:link 1 0 -36 2 :)<struct tag_file_name,std::string> file_name; .... try { if( FILE * fp=fopen("foo.txt","rt") ) { shared_ptr<FILE> f(fp,fclose); .... read_file(fp); //throws types deriving from boost::(:link 1 0 -35 2 :) do_something(); .... } else throw file_open_error() (:link 1 0 -7 2 |<<:) errno_code(errno); } catch( boost::(:link 1 0 -35 2 :) & e ) { e (:link 1 0 -7 2 |<<:) file_name("foo.txt"); throw; }@] Finally here is how the handler retrieves data from exceptions that derive from boost::(:link 1 0 -35 2 :): [@catch( io_error & e ) { std::cerr << "I/O Error!\n"; if( shared_ptr<std::string const> fn=(:link 1 0 -29 2 :)<file_name>(e) ) std::cerr << "File name: " << *fn << "\n"; if( shared_ptr<int const> c=(:link 1 0 -29 2 :)<errno_code>(e) ) std::cerr << "OS says: " << strerror(*c) << "\n"; }@] In addition, boost::(:link 1 0 -21 2 :) can be used to compose an automatic (if not user-friendly) message that contains all of the (:link 1 0 -36 2 :) objects added to a boost::(:link 1 0 -35 2 :).

The returned string is not presentable as a friendly user message, but because it is generated automatically, it is useful for debugging or logging purposes.

It supports transporting of arbitrary data to the catch site, which is otherwise tricky due to the no-throw requirements (15.5.1) for exception types. Data can be added to any exception object, either directly in the throw-expression (15.1), or at a later time as the exception object propagates up the call stack. The ability to add data to exception objects after they have been passed to throw is important, because often some of the information needed to handle an exception is unavailable in the context where the failure is detected.

This system is similar to (:link http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2179.html|N2179:), but because Boost Exception can not rely on language support, the use of (:link 1 0 -17 2 :) at the time of the throw is required in order to use cloning. !!!!Note: All exceptions emitted by the familiar function boost::(:link 1 0 -32 2 :) are guaranteed to derive from boost::(:link 1 0 -35 2 :) and to support cloning. (:include 1 0 -37 2 :) (:include 1 0 -13 2 :) 0 -32 13 2 (:auto !!!:) (:include synopsis:) !!!!Requirements: E must derive publicly from std::exception. !!!!Effects: * If BOOST_NO_EXCEPTIONS is not defined, boost::(:link 1 0 -32 2 :)(e) is equivalent to throw boost::(:link 1 0 -17 2 :)(boost::(:link 1 0 -8 2 :)(e)), unless BOOST_EXCEPTION_DISABLE is defined, in which case boost::(:link 1 0 -32 2 :)(e) is equivalent to throw e; * If BOOST_NO_EXCEPTIONS is defined, the function is left undefined, and the user is expected to supply an appropriate definition. Callers of (:link 1 0 -32 2 :) are allowed to assume that the function never returns; therefore, if the user-defined (:link 1 0 -32 2 :) returns, the behavior is undefined. 0 -33 1 2 (:auto !!!:) (:include synopsis:) !!!!Precondition: ep shall not be null. !!!!Throws: The exception to which ep refers. 0 -34 5 2 (:auto !!!:) Exception types should use virtual inheritance when deriving from other exception types. This insight is due to Andrew Koenig. Using virtual inheritance prevents ambiguity problems in the exception handler: [@#include <iostream> struct my_exc1 : std::exception { char const* what() const throw(); }; struct my_exc2 : std::exception { char const* what() const throw(); }; struct your_exc3 : my_exc1, my_exc2 {}; int main() { try { throw your_exc3(); } catch(std::exception const& e) {} catch(...) { std::cout << "whoops!" << std::endl; } }@] The program above outputs "whoops!" because the conversion to std::exception is ambiguous. The overhead introduced by virtual inheritance is always negligible in the context of exception handling. Note that virtual bases are initialized directly by the constructor of the most-derived-type (the type passed to the throw statement, in case of exceptions.) However, typically this detail is of no concern when boost::(:link 1 0 -35 2 :) is used, because it enables exception types to be trivial structs with no members (there's nothing to initialize.) See (:link 1 0 -11 2 mod="w":). 0 -35 13 2 (:auto !!!:) (:include synopsis:) Class boost::(:link 1 0 -35 2 :) is designed to be used as a universal base for user-defined exception types. An object of any type deriving from boost::(:link 1 0 -35 2 :) can store data of arbitrary types, using the (:link 1 0 -36 2 :) wrapper and (:link 1 0 -7 2 mod="/":). To retrieve data from a boost::(:link 1 0 -35 2 :) object, use the (:link 1 0 -29 2 :) function template. 0 -36 37 2 (:auto !!!:) (:include synopsis:) !!!!Requirements: T must have accessible copy constructor and must not be a reference (there is no requirement that T's copy constructor does not throw.) !!!!Description: This class template is used to associate a Tag type with a value type T. Objects of type (:link 1 0 -36 2 :)<Tag,T> can be passed to (:link 1 0 -7 2 mod="/":) to be stored in objects of type boost::(:link 1 0 -35 2 :). !!!!Usage: The header <(:link 1 0 -53 2 :)> provides a declaration of the (:link 1 0 -36 2 :) template, which is sufficient for the purpose of typedefing an instance for specific Tag and T, for example: [@#include <(:link 1 0 -53 2 :)> struct tag_errno; typedef boost::(:link 1 0 -36 2 :)<tag_errno,int> errno_info;@] Or, the shorter equivalent: [@#include <(:link 1 0 -53 2 :)> typedef boost::(:link 1 0 -36 2 :)<struct tag_errno,int> errno_info;@] This errno_info typedef can be passed to (:link 1 0 -7 2 mod="/":) (#include <(:link 1 0 -55 2 :)> first) to store an int named tag_errno in exceptions of types that derive from boost::(:link 1 0 -35 2 :): [@throw file_read_error() (:link 1 0 -7 2 |<<:) errno_info(errno);@] It can also be passed to 1 0 -29 2 (#include < 1 0 -24 2 > first) to retrieve the tag_errno int from a boost::(:link 1 0 -35 2 :): [@catch( boost::(:link 1 0 -35 2 :) & x ) { if( boost::shared_ptr<int const> e=boost:: 1 0 -29 2 <errno_info>(x) ) .... }@] 0 -37 11 2 (:auto !!!:) Here is how cloning can be enabled in a throw-expression (15.1): [@#include <(:link 1 0 -55 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 -35 2 :) { }; void file_read( FILE * f, void * buffer, size_t size ) { if( size!=fread(buffer,1,size,f) ) throw boost::(:link 1 0 -17 2 :)(file_read_error()) << errno_info(errno); }@] Of course, (:link 1 0 -17 2 :) may be used with any exception type; there is no requirement that it should derive from boost::(:link 1 0 -35 2 :). 0 -38 1 2 (:auto !!!:) (:include synopsis:) !!!!Requirements: This function must not be called outside of a catch block. !!!!Returns: A pointer of type E to the current exception object, or null if the current exception object can not be converted to E *. !!!!Throws: Nothing. 0 -39 13 2 (:auto !!!:) The code snippet below demonstrates how boost::(:link http://www.boost.org/libs/tuple/doc/tuple_users_guide.html|tuple:) can be used to bundle the name of the function that failed, together with the reported errno so that they can be added to exception objects more conveniently together: [@#include <(:link 1 0 -48 2 :)> #include <boost/shared_ptr.hpp> #include <stdio.h> #include <string> #include <errno.h> typedef boost::(:link 1 0 -36 2 :)<struct tag_file_name,std::string> file_name_info; typedef boost::(:link 1 0 -36 2 :)<struct tag_function,char const *> function_info; typedef boost::(:link 1 0 -36 2 :)<struct tag_errno,int> errno_info; typedef boost::tuple<function_info,errno_info> clib_failure; class file_open_error: public boost::(:link 1 0 -35 2 :) { }; boost::shared_ptr<FILE> file_open( char const * name, char const * mode ) { if( FILE * f=fopen(name,mode) ) return boost::shared_ptr<FILE>(f,fclose); else throw file_open_error() << file_name_info(name) << clib_failure("fopen",errno); }@] Note that the members of a boost::(:link http://www.boost.org/libs/tuple/doc/tuple_users_guide.html|tuple:) are stored separately in exception objects; they can only be retrieved individually, using (:link 1 0 -29 2 :). 0 -40 1 2 (:auto !!:) (:pagelist fmt="index" tags="type":) 0 -41 19 2 (:auto !!!:) Sometimes the throw site does not have all the information that is needed at the catch site to make sense of what went wrong. Let's say we have an exception type file_read_error, which takes a file name in its constructor. Consider the following function: [@void file_read( FILE * f, void * buffer, size_t size ) { if( size!=fread(buffer,1,size,f) ) throw file_read_error(????); }@] How can the file_read function pass a file name to the exception type constructor? All it has is a FILE handle. Using boost::(:link 1 0 -35 2 :) allows us to free the file_read function from the burden of storing the file name in exceptions it throws: [@#include <(:link 1 0 -49 2 :)> #include <stdio.h> #include <errno.h> typedef boost::(:link 1 0 -36 2 :)<struct tag_errno,int> errno_info; class file_read_error: public boost::(:link 1 0 -35 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 -49 2 :)> #include <boost/shared_ptr.hpp> #include <stdio.h> #include <string> typedef boost::(:link 1 0 -36 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 -35 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 -35 2 :) object, stores the file name, and re-throws using a throw-expression with no operand (15.1.6). The rationale for catching any boost::(:link 1 0 -35 2 :) object is that the file name is relevant to any failure that occurs in parse_file, ''even if the failure is unrelated to file I/O''. 0 -42 1 2 (:auto !!:) !!!Synopsis (:include synopsis:) 0 -43 17 2 (:auto !!!:) The following example demonstrates how errno can be stored in exception objects using Boost Exception: [@#include <(:link 1 0 -49 2 :)> #include <errno.h> #include <iostream> typedef boost::(:link 1 0 -36 2 :)<struct tag_errno,int> errno_info; //(1) class my_error: public boost::(:link 1 0 -35 2 :), public std::exception { }; //(2) void f() { throw my_error() << errno_info(errno); //(3) } @] First, we instantiate the (:link 1 0 -36 2 :) template using a unique identifier -- tag_errno, and the type of the info it identifies -- int. This provides compile-time type safety for the various values stored in exception objects. Second, we define class my_error, which derives from boost::(:link 1 0 -35 2 :). Finally, (3) illustrates how the typedef from (1) can be used with (:link 1 0 -7 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( int const * err=boost::(:link 1 0 -29 2 :)<errno_info>(x) ) std::cerr << "Error code: " << *err; } }@] The (:link 1 0 -29 2 :) function template is instantiated with the typedef from (1), and is passed an exception object of a polymorphic type.
