+</div>The diagnostic_information_what function is intended to be called from a user-defined std::exception::what() override. This allows diagnostic information to be returned as the what() string.
+<h4>Returns:</h4>
+A pointer to a zero-terminated buffer that contains a string similar to the std::string returned by the diagnostic_information function, or null to indicate a failure.
+<h4>Throws:</h4>
+Nothing.
+<h4>Note:</h4>
+The returned pointer becomes invalid if any error_info is modified or added to the exception object, or if another diagnostic information function is called.

!!!!Requirements:

* T must be a class with an accessible no-throw copy constructor.
* If T has any virtual base types, those types must have an accessible default 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>

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:

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>(:auto !!:)

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>

!!!Example:

(:include </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 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.

!!!Why is boost::exception abstract?

To prevent exception-neutral contexts from erroneously erasing the type of the original exception when adding (:link </string>

#include <stdexcept>

!!!What is the space overhead of the boost::exception base class?

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>

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>:) instance for transporting a relevant errno value in exceptions deriving from 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.

Using boost::(:link </string>
 <variant>1</variant>
 <weak_ptr>

 <shared_ptr>
- <id>-59</id>
+ <id>-42</id>
 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <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>:) 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>
 <expired>0</expired>
 <shared_ptr>
- <id>-20</id>
+ <id>-9</id>
 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <string>:), it is often desirable to add one or more (:link </string>
+ <string>:)>
#include <boost/shared_ptr.hpp>
#include <stdio.h>
#include <errno.h>

struct file_read_error: virtual boost::(:link </string>
 <variant>1</variant>
 <weak_ptr>
 <expired>0</expired>
 <shared_ptr>
- <id>-67</id>
+ <id>-42</id>
 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <string>:) objects in it. The syntactic sugar provided by (:link </string>
+ <string>:) { };

void
file_read( FILE * f, void * buffer, size_t size )
 {
 if( size!=fread(buffer,1,size,f) )
 throw file_read_error() << boost::(:link </string>
 <variant>1</variant>
 <weak_ptr>
 <expired>0</expired>
 <shared_ptr>
- <id>-45</id>
+ <id>-20</id>
 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <string>:) allows this to be done directly in a throw expression:

[@throw error() (:link </string>
+ <string>:)(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>
 <variant>1</variant>
 <weak_ptr>
 <expired>0</expired>
 <shared_ptr>
- <id>-45</id>
+ <id>-9</id>
 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <string>|<<:) foo_info(foo) (:link </string>
+ <string>:)>
#include <boost/shared_ptr.hpp>
#include <stdio.h>
#include <string>

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 </string>
 <variant>1</variant>
 <weak_ptr>
 <expired>0</expired>
 <shared_ptr>
- <id>-45</id>
+ <id>-42</id>
 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <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>
+ <string>:) & e )
 {
 e << boost::(:link </string>
 <variant>1</variant>
 <weak_ptr>
 <expired>0</expired>
 <shared_ptr>
- <id>-45</id>
+ <id>-43</id>
 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <string>|<<:) file_name(fn);@]

The intention here is to throw a file_open_error, however if (:link </string>
+ <string>:)(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>
 <variant>1</variant>
 <weak_ptr>
 <expired>0</expired>
 <shared_ptr>

 </weak_ptr>

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

- <id>-67</id>
+ <id>-42</id>
 </shared_ptr>
 </weak_ptr>

- <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>

An object of any type deriving from boost::(:link </string>

To retrieve data from a boost::(: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>
+ <string>:) function predates the Boost Exception library and there has been some concern about its current behavior of injecting boost::(:link </string>

!!!!Note:

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

 </weak_ptr>

- <string>:) are guaranteed to derive from boost::(:link </string>
+ <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>
 <variant>1</variant>
 <weak_ptr>
 <expired>0</expired>
 <shared_ptr>
- <id>-20</id>

 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <string>:) and to support cloning.

(:include </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>
 <variant>1</variant>

+ <id>-55</id>

(:include </string>
+ <string>:), but this requires that Boost Serialization throws exceptions using boost::(:link </string>

#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.

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?

->''"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.

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>(:auto !!:)

Boost Exception provides a namespace-scope function (:link </string>
 <variant>1</variant>
 <weak_ptr>

 <shared_ptr>
- <id>-20</id>
+ <id>-58</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>:) which takes a boost::(:link </string>
 <variant>1</variant>
 <weak_ptr>

 <shared_ptr>
- <id>-53</id>
+ <id>-42</id>
 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <string>:)>
#include <boost/shared_ptr.hpp>
#include <stdio.h>
#include <errno.h>

struct file_read_error: virtual boost::(:link </string>
+ <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>-20</id>
+ <id>-42</id>
 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <string>:) { };

void
file_read( FILE * f, void * buffer, size_t size )
 {
 if( size!=fread(buffer,1,size,f) )
 throw file_read_error() << boost::(:link </string>
+ <string>:) through (:link </string>
 <variant>1</variant>
 <weak_ptr>
 <expired>0</expired>
 <shared_ptr>
- <id>-36</id>
+ <id>-7</id>
 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <string>:)(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>
+ <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:

[@#include <(:link </string>
 <variant>1</variant>
 <weak_ptr>
 <expired>0</expired>

void file_read( FILE * f, void * buffer, size_t size );

void

 {
 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>

#include <iostream>

void f(); //throws unknown types that derive 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>

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>(:auto !!!:)

!!!!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>

 </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>:)<Tag,T> can be passed to (:link </string>

 }@]

In a higher exception-neutral context, we add the file name to ''any'' exception that derives from boost::(:link </string>
+ <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>-20</id>
+ <id>-31</id>

- <string>:):

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

struct tag_errno;
typedef boost::(:link </string>
 <variant>1</variant>

- <id>-67</id>

 </shared_ptr>
 </weak_ptr>

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

Or, the shorter equivalent:

[@#include <(:link </string>

 <shared_ptr>

 do_something();

 else
 throw file_open_error() (:link </string>

 }
catch( boost::(: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:

[@struct exception_base: virtual std::exception, virtual boost::(:link </string>
+ <string>:) typedefs, ready for use with (:link </string>

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.

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>-58</id>
+ <id>-42</id>
 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <string>:) (#include <(: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>
 <weak_ptr>
 <expired>0</expired>
 <shared_ptr>
- <id>-31</id>
+ <id>-42</id>
 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <string>:)> first) to retrieve the tag_errno int from a boost::(:link </string>
+ <string>:) { };
struct io_error: virtual exception_base { };
struct file_read_error: virtual io_error { };

typedef boost::(:link </string>
 <variant>1</variant>
 <weak_ptr>
 <expired>0</expired>
 <shared_ptr>
- <id>-20</id>
+ <id>-48</id>
 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <string>:):

[@catch( boost::(:link </string>
+ <string>:)<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 </string>
 <variant>1</variant>
 <weak_ptr>
 <expired>0</expired>
 <shared_ptr>
- <id>-20</id>
+ <id>-7</id>
 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <string>:) & x )
 {
 if( int const * e=boost::(:link </string>
+ <string>|<<:) errno_code(errno);
 ....
 }@]

In a higher exception-neutral context, we add the file name to ''any'' exception that derives from boost::(:link </string>
 <variant>1</variant>
 <weak_ptr>
 <expired>0</expired>
 <shared_ptr>
- <id>-58</id>
+ <id>-42</id>
 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <string>:)<errno_info>(x) )
 ....
 }@]

For convenience and uniformity, Boost Exception defines the following commonly used (:link </string>
+ <string>:):

[@typedef boost::(:link </string>
 <variant>1</variant>
 <weak_ptr>
 <expired>0</expired>
 <shared_ptr>
- <id>-67</id>

 </weak_ptr>

- <string>:) typedefs, ready for use with (:link </string>
+ <string>:)<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 </string>

 <weak_ptr>
 <expired>0</expired>

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>
+ <string>:)
 do_something();
 ....
 }
 else
 throw file_open_error() (:link </string>
 <variant>1</variant>
 <weak_ptr>
 <expired>0</expired>

- <id>-58</id>
+ <id>-7</id>

 </weak_ptr>
 <variant>2</variant>
- <string>:) function template can be called with any exception type. If BOOST_NO_RTTI is defined, (:link </string>
+ <string>|<<:) errno_code(errno);
 }
catch( boost::(:link </string>
 <variant>1</variant>
 <weak_ptr>

 <shared_ptr>

+ <id>-42</id>
 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <string>:) can be used only with objects of type boost::(:link </string>
+ <string>:) & e )
 {
 e (:link </string>
 <variant>1</variant>

 <shared_ptr>
- <id>-20</id>
+ <id>-7</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>
+ <string>|<<:) file_name("foo.txt");
 throw;
 }@]

Finally here is how the handler retrieves data from exceptions that derive from boost::(:link </string>

 <shared_ptr>
- <id>-32</id>
+ <id>-42</id>

- <string>:) and (:link </string>
+ <string>:):

[@catch( io_error & e )
 {
 std::cerr << "I/O Error!\n";

 if( std::string const * fn=(:link </string>
 <variant>1</variant>
 <weak_ptr>
 <expired>0</expired>
 <shared_ptr>
- <id>-11</id>
+ <id>-19</id>

 </weak_ptr>
 <variant>2</variant>
- <string>:) are integrated directly in the (:link </string>
+ <string>:)<file_name>(e) )
 std::cerr << "File name: " << *fn << "\n";

 if( int const * c=(:link </string>

 <weak_ptr>

 <shared_ptr>
- <id>-59</id>
+ <id>-19</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>
+ <string>:)<errno_code>(e) )
 std::cerr << "OS says: " << strerror(*c) << "\n";
 }@]

In addition, boost::(:link </string>

 <shared_ptr>
- <id>-56</id>
+ <id>-58</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>
