-<h2>Introduction</h2>
+<div class="RenoIncludeDIV"><h2>Introduction</h2>
<p>The purpose of Boost Exception is to ease the design of exception class hierarchies and to help write exception handling and error reporting code.</p>
<p>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.</p>
<p>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. </p>

-</div><h4>Requirements:</h4>
-<p>T must have accessible copy constructor and must not be a reference (there is no requirement that T's copy constructor does not throw.)</p>
-<h4>Description:</h4>
-<p>This class template is used to associate a Tag type with a value type T. Objects of type <span class="RenoLink">error_info</span><Tag,T> can be passed to <span class="RenoLink">operator<<</span> to be stored in objects of type boost::<span class="RenoLink">exception</span>.</p>
-<h4>Usage:</h4>
-<p>The header <<span class="RenoLink">boost/exception/error_info.hpp</span>> provides a declaration of the <span class="RenoLink">error_info</span> template, which is sufficient for the purpose of typedefing an instance for specific Tag and T, for example:</p>
-<pre>#include <<span class="RenoLink">boost/exception/error_info.hpp</span>>
-
-struct tag_errno;
-typedef boost::<span class="RenoLink">error_info</span><tag_errno,int> errno_info;</pre>
-<p>Or, the shorter equivalent:</p>
-<pre>#include <<span class="RenoLink">boost/exception/error_info.hpp</span>>
-
-typedef boost::<span class="RenoLink">error_info</span><struct tag_errno,int> errno_info;</pre>
-<p>This errno_info typedef can be passed to <span class="RenoLink">operator<<</span> (#include <<span class="RenoLink">boost/exception/info.hpp</span>> first) to store an int named tag_errno in exceptions of types that derive from boost::<span class="RenoLink">exception</span>:</p>
-<pre>throw file_read_error() <span class="RenoLink"><<</span> errno_info(errno);</pre>
-<p>It can also be passed to <span class="RenoLink">get_error_info</span> (#include <<span class="RenoLink">boost/exception/get_error_info.hpp</span>> first) to retrieve the tag_errno int from a boost::<span class="RenoLink">exception</span>:</p>

-<h4>Returns:</h4>
-<p>An object of <i>unspecified</i> type which derives publicly from T. That is, the returned object can be intercepted by a catch(T &).</p>
-<h4>Description:</h4>
-<p>This function is designed to be used directly in a throw-expression to enable the <span class="RenoLink">exception_ptr</span> support in Boost Exception. For example:</p>
-<pre>class
-my_exception:
- public std::exception
- {
- };
-
-....
-throw boost::<span class="RenoLink">enable_current_exception</span>(my_exception());</pre>
-<p>Unless <span class="RenoLink">enable_current_exception</span> is called at the time an exception object is used in a throw-expression, an attempt to copy it using <span class="RenoLink">current_exception</span> may return an <span class="RenoLink">exception_ptr</span> which refers to an instance of <span class="RenoLink">unknown_exception</span>. See <span class="RenoLink">current_exception</span> for details.</p>
-<h4>Note:</h4>
-<p>Instead of using the throw keyword directly, it is preferable to call boost::<span class="RenoLink">throw_exception</span>. This is guaranteed to throw an exception that derives from boost::<span class="RenoLink">exception</span> and supports the <span class="RenoLink">exception_ptr</span> functionality.</p>

-<h4>Notes:</h4>
-<div><ul><li> It is unspecified whether the return values of two successive calls to <span class="RenoLink">current_exception</span> refer to the same exception object.</li>

If <span class="RenoLink">enable_current_exception</span> was not used, and if the compiler does not provide the necessary support, then <span class="RenoLink">current_exception</span> may return an <span class="RenoLink">exception_ptr</span> that refers to an instance of <span class="RenoLink">unknown_exception</span>. In this case, if the original exception object derives from boost::<span class="RenoLink">exception</span>, then the boost::<span class="RenoLink">exception</

- <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>

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

* 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 </string>

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 </string>

                                                                                                         </weak_ptr>

struct io_error: virtual exception_base { };
struct file_error: virtual io_error { };
struct read_error: virtual io_error { };

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

Boost Exception responds to the following configuration macros:

'''BOOST_NO_RTTI'''\\

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:

!!!!Requirements:

T must be a class with an accessible no-throw copy constructor.

!!!!Returns:

An object of ''unspecified'' type which derives publicly from T. That is, the returned object can be intercepted by a catch(T &).

This function is designed to be used directly in a throw-expression to enable 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.

Using boost::</string>
+ <string>:) support in Boost Exception. For example:

[@class
my_exception:
 public std::exception
 {
 };

....
throw boost::(:link </string>

                                                                                                                 <expired>0</expired>

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>

*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 </string>
+ <variant>1</variant>
+ <weak_ptr>

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>-30</id>
- </shared_ptr>
- </weak_ptr>
+ <size>29</size>
                                                                                                         <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:

[@struct exception_base: virtual std::exception, virtual boost::(:link </string>
+ <string>(:auto !!!:)

- <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> from a top-level function to output diagnostic information about unhandled exceptions:

[@int
main()
 {
 try
 {
 run_program();
 }
 catch(
 error & e )
 {
 //handle error
 }

+ <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>

- <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.

!!!Should I call boost::throw_exception or BOOST_THROW_EXCEPTION?

It is preferable to throw exceptions using the (:link </string>
+ <string>:)

Boost Exception provides a namespace-scope function (:link </string>

Boost Exception supports transporting of exception objects between threads through cloning. 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 </string>

 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 </string>

The string representation of each (:link </string>

!!!!Notes:

*The format of the returned string is unspecified.
*The returned string is ''not'' user-friendly.
*If dynamic_cast<std::exception const *>(&x) is not null, the returned string includes the output from std::exception::what.
*The returned string may include additional platform-specific diagnostic information.

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>
