<h3>Why is boost::exception integrated in boost::throw_exception?</h3>
<p>The boost::<span class="RenoLink">throw_exception</span> function predates the Boost Exception library and there has been some concern about its current behavior of injecting boost::<span class="RenoLink">exception</span> as a base of any exception passed to boost::<span class="RenoLink">throw_exception</span>. 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.</p>
<p>The problem is that users of Boost Exception can't by themselves cause a library to throw types that derive from boost::<span class="RenoLink">exception</span>, and without this they can't use any of the Boost Exception facilities.</p>

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.

- <string>!!Introduction

The purpose of Boost Exception is to ease the design of exception class hierarchies and to help write exception handling and error reporting code.

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. 

Boost Exception also supports (:link http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2179.html|N2179:)-style (:link </string>

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(???);
 ....&#
10; }@]

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 exce
ption 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 </string>
- <variant>1</variant>
- <weak_ptr>
- <expired>0</expired>
- <shared_ptr>
- <id>-13</id>
- </shared_ptr>
- </weak_ptr>
- <variant>2</variant>
- <string>:).
*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:

[@typedef boost::(:link </string>

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 pass
ed to the throw statement, in case of exceptions.) However, typically this detail is of no concern when boost::(:link </string>

First, we instantiate the (:link </string>
+ <string>:) function with such user-defined types would introduce dangerous ambiguity which would break all catch(std::exception &) statements.

Of course, boost::(:link </string>
                                                                                                         <variant>1</variant>
                                                                                                         <weak_ptr>
                                                                                                                 <expired>0</expired>
                                                                                                                 <shared_ptr>
- <id>-44</id>
+ <id>-16</id>
                                                                                                                 </shared_ptr>
                                                                                                         </weak_ptr>
                                                                                                         <variant>2</variant>
- <string>:) 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 </string>
+ <string>:) 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.)

!!!Why is boost::exception abstract?

To prevent exception-neutral contexts from erroneously erasing the type of the original exception when adding (:link </string>
                                                                                                         <variant>1</variant>
                                                                                                         <weak_ptr>
                                                                                                                 <expired>0</expired>
                                                                                                                 <shared_ptr>
- <id>-13</id>
+ <id>-67</id>
                                                                                                                 </shared_ptr>
                                                                                                         </weak_ptr>
                                                                                                         <variant>2</variant>
- <string>:).

Finally, (3) illustrates how the typedef from (1) can be used with (:link </string>
+ <string>:) to an active exception object:

[@catch( boost::(:link </string>
                                                                                                         <variant>1</variant>
                                                                                                         <weak_ptr>
                                                                                                                 <expired>0</expired>
                                                                                                                 <shared_ptr>

                                                                                                         </weak_ptr>
                                                                                                         <variant>2</variant>

The stored errno value can be recovered at a later time like this:

!!!Why doesn't boost::exception derive from std::exception?

Despite that (:link </string>
+ <string>:), 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 </string>

- <string>:) function with such user-defined types would introduce dangerous ambiguity which would break all catch(std::exception &) statements.

Of course, boost::(:link </string>
+ <string>:) 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.

The correct code is:

[@catch( boost::(:link </string>
+ <string>|<<:) 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 operator<< allowed to throw?

This question is referring to the following issue. Consider this throw statement example:

[@throw file_open_error() (:link </string>
                                                                                                         <variant>1</variant>

                                                                                                         </weak_ptr>

The intention here is to throw a file_open_error, however if (:link </string>

!!!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 </string>
+ <string> mod="/":) fails to copy the std::string contained in the file_name (:link </string>
                                                                                                         <variant>1</variant>

+ <string>:) wrapper, a std::bad_alloc could propagate instead. This behavior seems undesirable to some programmers.

Bjarne Stroustrup, The C++ Programming Language, 3rd Edition, page 371:

->''"Throwing an exception requires an object to throw. A C++ implementation is required to have enough spare memory to be able to throw bad_alloc in case of memory exhaustion. However, it is possible that throwing some other exception will cause memory exhaustion."''

So, an attempt to throw any exception may already result in propagating std::bad_alloc instead.

- <string>:) 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.

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.

and looks better than something like:

[@throw error().add(foo_info(foo)).add(bar_info(bar));@]

- <string> wrapper, a std::bad_alloc could propagate instead. This behavior seems undesirable to some programmers.

Bjarne Stroustrup, The C++ Programming Language, 3rd Edition, page 371:

->''"Throwing an exception requires an object to throw. A C++ implementation is required to have enough spare memory to be able to throw bad_alloc in case of memory exhaustion. However, it is possible that throwing some other exception will cause memory exhaustion."''

So, an attempt to throw any exception may already result in propagating std::bad_alloc instead.

The (:link </string>
+ <string>(: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.

The purpose of Boost Exception is to ease the design of exception class hierarchies and to help write exception handling and error reporting code.

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. 

Boost Exception also supports (:link http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2179.html|N2179:)-style (:link </string>

- <string>(: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 </string>
+ <string>(: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(???);
 ....&#
10; }@]

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 exce
ption 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 </string>

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 pass
ed to the throw statement, in case of exceptions.) However, typically this detail is of no concern when boost::(:link </string>
+ <string>:) 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 </string>
                                                                                                         <variant>1</variant>

- <string>:) is used, because it enables exception types to be trivial structs with no members (there's nothing to initialize.) See (:link </string>
+ <string>:), 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:

Using this approach, exception types become a simple tagging system for categorizing errors and selecting failures in exception handlers.

The following example demonstrates how errno can be stored in exception objects using Boost Exception:

[@#include <(:link </string>
+ <variant>1</variant>
+ <weak_ptr>

+ <id>-51</id>

#include <iostream>

typedef boost::(:link </string>
+ <variant>1</variant>
+ <weak_ptr>

+ <id>-67</id>
+ </shared_ptr>
+ </weak_ptr>
+ <variant>2</variant>
+ <string>:)<struct tag_my_info,int> my_info; //(1)

struct my_error: virtual boost::(:link </string>

+ <weak_ptr>
+ <expired>0</expired>
+ <shared_ptr>
+ <id>-16</id>
+ </shared_ptr>

+ <variant>2</variant>
+ <string>:), virtual std::exception { }; //(2)

void
f()
 {
 throw my_error() << my_info(42); //(3)
 }@]

First, we instantiate the (:link </string>
+ <variant>1</variant>
+ <weak_ptr>
+ <expired>0</expired>
+ <shared_ptr>
+ <id>-67</id>
+ </shared_ptr>
+ </weak_ptr>
+ <variant>2</variant>
+ <string>:) template using a unique identifier -- tag_my_info, 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 </string>
+ <variant>1</variant>
+ <weak_ptr>
+ <expired>0</expired>
+ <shared_ptr>
+ <id>-16</id>
+ </shared_ptr>
+ </weak_ptr>
+ <variant>2</variant>
+ <string>:).

Finally, (3) illustrates how the typedef from (1) can be used with (:link </string>
+ <variant>1</variant>
+ <weak_ptr>
+ <expired>0</expired>
+ <shared_ptr>
+ <id>-43</id>
+ </shared_ptr>
+ </weak_ptr>
+ <variant>2</variant>
+ <string>|operator<<:) to store values in exception objects at the point of the throw.

The stored my_info value can be recovered at a later time like this:

[@// ...continued

void
g()
 {
 try
 {
 f();
 }
 catch(
 my_error & x )
 {
 if( int const * mi=boost::(:link </string>

+ </weak_ptr>
+ <variant>2</variant>
+ <string>:)<my_info>(x) )
 std::cerr << "My info: " << *mi;
 }
 }@]

The (:link </string>

+ </shared_ptr>
+ </weak_ptr>
+ <variant>2</variant>
+ <string>:) 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, err will point to it; otherwise a null pointer is returned.

(: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 </string>
+ <variant>1</variant>
+ <weak_ptr>
+ <expired>0</expired>
+ <shared_ptr>
+ <id>-67</id>
+ </shared_ptr>
+ </weak_ptr>
+ <variant>2</variant>
+ <string>:)<Tag,T> can be passed to (:link </string>
+ <variant>1</variant>
+ <weak_ptr>
+ <expired>0</expired>
+ <shared_ptr>
+ <id>-43</id>
+ </shared_ptr>
+ </weak_ptr>
+ <variant>2</variant>
+ <string> mod="/":) to be stored in objects of type boost::(:link </string>
+ <variant>1</variant>
+ <weak_ptr>
+ <expired>0</expired>
+ <shared_ptr>
+ <id>-16</id>
+ </shared_ptr>
+ </weak_ptr>
+ <variant>2</variant>
+ <string>:).

!!!!Usage:

The header <(:link </string>
+ <variant>1</variant>
+ <weak_ptr>
+ <expired>0</expired>
+ <shared_ptr>
+ <id>-60</id>
+ </shared_ptr>
+ </weak_ptr>
+ <variant>2</variant>
+ <string>:)> provides a declaration of the (:link </string>
+ <variant>1</variant>
+ <weak_ptr>
+ <expired>0</expired>
+ <shared_ptr>
+ <id>-67</id>
+ </shared_ptr>
+ </weak_ptr>
+ <variant>2</variant>
+ <string>:) template, which is sufficient for the purpose of typedefing an instance for specific Tag and T, for example:

[@#include <(:link </string>
+ <variant>1</variant>
+ <weak_ptr>
+ <expired>0</expired>
+ <shared_ptr>
+ <id>-60</id>
+ </shared_ptr>
+ </weak_ptr>
+ <variant>2</variant>
+ <string>:)>

struct tag_errno;
typedef boost::(:link </string>
+ <variant>1</variant>
+ <weak_ptr>
+ <expired>0</expired>
+ <shared_ptr>
+ <id>-67</id>
+ </shared_ptr>
+ </weak_ptr>
+ <variant>2</variant>
+ <string>:)<tag_errno,int> errno_info;@]

Or, the shorter equivalent:

[@#include <(:link </string>
+ <variant>1</variant>
+ <weak_ptr>
+ <expired>0</expired>
+ <shared_ptr>
+ <id>-60</id>
+ </shared_ptr>
+ </weak_ptr>
+ <variant>2</variant>
+ <string>:)>

typedef boost::(:link </string>
+ <variant>1</variant>
+ <weak_ptr>
+ <expired>0</expired>
+ <shared_ptr>
+ <id>-67</id>
+ </shared_ptr>
+ </weak_ptr>
+ <variant>2</variant>
+ <string>:)<struct tag_errno,int> errno_info;@]

This errno_info typedef can be passed to (:link </string>
+ <variant>1</variant>
+ <weak_ptr>
+ <expired>0</expired>
+ <shared_ptr>
+ <id>-43</id>
+ </shared_ptr>

+ <expired>0</expired>
+ <shared_ptr>
+ <id>-71</id>
+ </shared_ptr>
+ </weak_ptr>
+ <variant>2</variant>
+ <string>:)> first) to store an int named tag_errno in exceptions of types that derive from boost::(:link </string>
+ <variant>1</variant>
+ <weak_ptr>
+ <expired>0</expired>
+ <shared_ptr>
+ <id>-16</id>
+ </shared_ptr>

It can also be passed to (:link </string>

+ <weak_ptr>

+ <variant>2</variant>
+ <string>:)> first) to retrieve the tag_errno int from a boost::(:link </string>
+ <variant>1</variant>
+ <weak_ptr>
+ <expired>0</expired>
+ <shared_ptr>
+ <id>-16</id>
+ </shared_ptr>

For convenience and uniformity, Boost Exception defines the following commonly used (:link </string>
+ <variant>1</variant>
+ <weak_ptr>
+ <expired>0</expired>
+ <shared_ptr>
+ <id>-67</id>
+ </shared_ptr>
+ </weak_ptr>

+ <variant>1</variant>
+ <weak_ptr>
+ <expired>0</expired>
+ <shared_ptr>
+ <id>-43</id>
+ </shared_ptr>
+ </weak_ptr>
+ <variant>2</variant>
+ <string> mod="/":):

(:pagelist tags="error_info_instance":)
</string>
+ </container>
+ </pair>

Boost Exception responds to the following configuration macros:

'''BOOST_NO_RTTI'''\\
'''BOOST_NO_TYPEID'''

The first macro prevents Boost Exception from using dynamic_cast and dynamic typeid. 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 </string>
+ <variant>1</variant>
+ <weak_ptr>
+ <expired>0</expired>
+ <shared_ptr>
+ <id>-56</id>
+ </shared_ptr>
+ </weak_ptr>
+ <variant>2</variant>
+ <string>:) function template can be called with any exception type. If BOOST_NO_RTTI is defined, (:link </string>
+ <variant>1</variant>
+ <weak_ptr>
+ <expired>0</expired>
+ <shared_ptr>
+ <id>-56</id>
+ </shared_ptr>
+ </weak_ptr>
+ <variant>2</variant>
+ <string>:) can be used only with objects of type boost::(:link </string>
+ <variant>1</variant>
+ <weak_ptr>
+ <expired>0</expired>
+ <shared_ptr>
+ <id>-16</id>
+ </shared_ptr>
+ </weak_ptr>
+ <variant>2</variant>
+ <string>:).

!!!!Note:

The library needs RTTI functionality. Disabling the language RTTI support enables an internal RTTI system, which may have more or less overhead depending on the platform.

'''BOOST_EXCEPTION_DISABLE'''

By default, (:link </string>
+ <variant>1</variant>
+ <weak_ptr>
+ <expired>0</expired>
+ <shared_ptr>
+ <id>-28</id>
+ </shared_ptr>
+ </weak_ptr>
+ <variant>2</variant>
+ <string>:) and (:link </string>
+ <variant>1</variant>
+ <weak_ptr>
+ <expired>0</expired>
+ <shared_ptr>
+ <id>-6</id>
+ </shared_ptr>
+ </weak_ptr>
+ <variant>2</variant>
+ <string>:) are integrated directly in the (:link </string>
+ <variant>1</variant>
+ <weak_ptr>
+ <expired>0</expired>
+ <shared_ptr>
+ <id>-57</id>
+ </shared_ptr>
+ </weak_ptr>
+ <variant>2</variant>
+ <string>:) 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 </string>
+ <variant>1</variant>
+ <weak_ptr>
+ <expired>0</expired>
+ <shared_ptr>
+ <id>-54</id>
+ </shared_ptr>
+ </weak_ptr>
+ <variant>2</variant>
+ <string>:).

'''BOOST_NO_EXCEPTIONS'''

This macro disables exception handling in Boost, forwarding all exceptions to a user-defined non-template version of boost::</string>
+ <variant>1</variant>
+ <weak_ptr>
+ <expired>0</expired>
+ <shared_ptr>
+ <id>-57</id>
+ </shared_ptr>
+ </weak_ptr>
+ <variant>2</variant>
+ <string>. However, unless BOOST_EXCEPTION_DISABLE is also defined, users can still examine the exception object for any data added at the point of the throw, or use boost::</string>
+ <variant>1</variant>
+ <weak_ptr>
+ <expired>0</expired>
+ <shared_ptr>
+ <id>-61</id>
+ </shared_ptr>
+ </weak_ptr>
+ <variant>2</variant>
+ <string> (of course under BOOST_NO_EXCEPTIONS, the user-defined boost::throw_exception is not allowed to return to the caller.)
</string>
+ </container>
+ </pair>
+ <pair>
+ <weak_ptr>
+ <expired>0</expired>
+ <shared_ptr>
+ <id>-69</id>
+ </shared_ptr>
+ </weak_ptr>
+ <container>
+ <size>11</size>
+ <variant>2</variant>
+ <string>(:auto !!:)

All exception types that derive from boost::(:link </string>
+ <variant>1</variant>
+ <weak_ptr>
+ <expired>0</expired>
+ <shared_ptr>
+ <id>-16</id>
+ </shared_ptr>
+ </weak_ptr>
+ <variant>2</variant>
+ <string>:) can be used as type-safe containers of arbitrary data objects, while complying with the no-throw requirements (15.5.1) of the ANSI C++ standard for exception types.

When exceptions derive from boost::(:link </string>
+ <variant>1</variant>
+ <weak_ptr>
+ <expired>0</expired>
+ <shared_ptr>
+ <id>-16</id>
+ </shared_ptr>
+ </weak_ptr>
+ <variant>2</variant>
+ <string>:), 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.

Boost Exception provides a namespace-scope function (:link </string>
+ <variant>1</variant>
+ <weak_ptr>
+ <expired>0</expired>
+ <shared_ptr>
+ <id>-61</id>
+ </shared_ptr>
+ </weak_ptr>
+ <variant>2</variant>
+ <string>:) which takes a boost::(:link </string>
+ <variant>1</variant>
+ <weak_ptr>
+ <expired>0</expired>
+ <shared_ptr>
+ <id>-16</id>
+ </shared_ptr>
+ </weak_ptr>
+ <variant>2</variant>
+ <string>:). The returned string contains:

*the string representation of all data objects added to the boost::(:link </string>
+ <variant>1</variant>
+ <weak_ptr>
+ <expired>0</expired>
+ <shared_ptr>
+ <id>-16</id>
+ </shared_ptr>
+ </weak_ptr>
+ <variant>2</variant>

+ <string> mod="/":);
*the output from std::exception::what;
*additional platform-specific diagnostic information.

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. Here is an example:
