<li> It is illegal for multiple threads to modify the same exception_ptr object concurrently.</li>
<li> While calling current_exception 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 rethrow_exception concurrently to throw the same exception object into multiple threads.</li>

-<h4>Nesting of exceptions</h4>
+<h4>Nesting of exceptions:</h4>
An exception_ptr can be added as error_info to any boost::exception. This is a convenient way to nest exceptions. There is no limit on the depth of the nesting, however cyclic references result in undefined behavior.

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

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>
+ <string>|<<:) foo_info(foo);
 throw e; //Compile error: boost::(:link </string>
 <variant>1</variant>
 <weak_ptr>
 <expired>0</expired>
 <shared_ptr>
- <id>-47</id>
+ <id>-50</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:

[@struct exception_base: virtual std::exception, virtual boost::(:link </string>
+ <string>:) is abstract
 }@]

The correct code is:

[@catch( boost::(:link </string>
 <variant>1</variant>

Some exception hierarchies can not be modified to make boost::(: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>:) anyway. Here is an example:

[@#include <(: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.

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>

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

- <string>:). 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 </string>
+ <string>(:auto !!!:)

(:include decl:)

!!!!Effects:

* Default constructor: initializes an empty boost::(:link </string>
 <variant>1</variant>

 <shared_ptr>
- <id>-47</id>
+ <id>-50</id>
 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <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>:) object.
* Copy constructor: initializes a boost::(:link </string>
 <variant>1</variant>
 <weak_ptr>
 <expired>0</expired>
 <shared_ptr>
- <id>-33</id>
+ <id>-50</id>
 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <string>:), but this requires that Boost Serialization throws exceptions using boost::(:link </string>
+ <string>:) object which shares ownership with x of all data added through (:link </string>
 <variant>1</variant>
 <weak_ptr>

 <shared_ptr>
- <id>-37</id>
+ <id>-52</id>

- <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.

!!!Why use operator<< overload for adding info to exceptions?

Before throwing an object of type that derives from boost::(:link </string>
+ <string>(:auto !!:)

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>
 <variant>1</variant>
 <weak_ptr>
 <expired>0</expired>
 <shared_ptr>
- <id>-47</id>
+ <id>-38</id>
 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <string>:), it is often desirable to add one or more (:link </string>
+ <string>:) at the time of the throw is required in order to use cloning.

!!!!Note:

All exceptions emitted by the familiar function boost::(:link </string>
 <variant>1</variant>
 <weak_ptr>

 <shared_ptr>
- <id>-52</id>
+ <id>-36</id>

- <string>:) allows this to be done directly in a throw expression:

[@throw error() (:link </string>

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 </string>
+ <string>:)<struct tag_std_range_max,size_t> std_range_max;
typedef boost::(:link </string>
 <variant>1</variant>
 <weak_ptr>
 <expired>0</expired>
 <shared_ptr>
- <id>-47</id>
+ <id>-14</id>
 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <string>:) allows us to free the file_read function from the burden of storing the file name in exceptions it throws:

[@#include <(:link </string>
+ <string>:)<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 </string>
 <variant>1</variant>
 <weak_ptr>
 <expired>0</expired>
 <shared_ptr>
- <id>-22</id>
+ <id>-26</id>
 </shared_ptr>
 </weak_ptr>

#include <stdio.h>
#include <errno.h>

typedef boost::(:link </string>
+ <string>:)(std::range_error("Index out of range")) <<
 std_range_min(0) <<
 std_range_max(size()) <<
 std_range_index(i);
 //....
 }
 };
@]

The call to (:link </string>
 <variant>1</variant>
 <weak_ptr>
 <expired>0</expired>
 <shared_ptr>
- <id>-52</id>
+ <id>-26</id>
 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <string>:)<struct tag_errno,int> errno_info;

class file_read_error: public boost::(:link </string>
+ <string>:)<T> gets us an object of ''unspecified type'' which is guaranteed to derive from both boost::(:link </string>
 <variant>1</variant>
 <weak_ptr>

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 </string>

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 </string>

 {
 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 </string>

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.

 </weak_ptr>

- <string>:)<tag_errno,int> errno_info;@]

Or, the shorter equivalent:

[@#include <(:link </string>
+ <string>:) allows us to free the file_read function from the burden of storing the file name in exceptions it throws:

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

+ <id>-14</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>
+ <string>:)<struct tag_errno,int> errno_info;

class file_read_error: public boost::(:link </string>
 <variant>1</variant>

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 </string>

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(

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

 {
 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 </string>

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.

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>-46</id>
+ <id>-50</id>
 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <string> mod="w":)
##(:link </string>
+ <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>
