Detailed Description

Classes and functions for reporting errors via exception classes.


Typedef Documentation

typedef void(* std::terminate_handler)()

If you write a replacement terminate handler, it must be of this type.

Definition at line 89 of file exception.

typedef void(* std::unexpected_handler)()

If you write a replacement unexpected handler, it must be of this type.

Definition at line 92 of file exception.


Function Documentation

A replacement for the standard terminate_handler which prints more information about the terminating exception (if any) on stderr.

Call

to use. For more info, see http://gcc.gnu.org/onlinedocs/libstdc++/manual/bk01pt02ch06s02.html

In 3.4 and later, this is on by default.

template<typename _Ex >
exception_ptr std::copy_exception ( _Ex  __ex)

Obtain an exception_ptr pointing to a copy of the supplied object.

Definition at line 167 of file exception_ptr.h.

References std::current_exception().

exception_ptr std::current_exception ( )

Obtain an exception_ptr to the currently handled exception. If there is none, or the currently handled exception is foreign, return the null value.

Referenced by std::copy_exception().

template<typename _Ex >
exception_ptr std::make_exception_ptr ( _Ex  __ex)

Obtain an exception_ptr pointing to a copy of the supplied object.

Definition at line 186 of file exception_ptr.h.

void std::rethrow_exception ( exception_ptr  )

Throw the object pointed to by the exception_ptr.

template<typename _Ex >
void std::rethrow_if_nested ( const _Ex &  __ex) [inline]

If __ex is derived from nested_exception, __ex.rethrow_nested().

Definition at line 146 of file nested_exception.h.

void std::rethrow_if_nested ( const nested_exception &  __ex) [inline]

Overload, See N2619.

Definition at line 154 of file nested_exception.h.

terminate_handler std::set_terminate ( terminate_handler  )

Takes a new handler function as an argument, returns the old function.

unexpected_handler std::set_unexpected ( unexpected_handler  )

Takes a new handler function as an argument, returns the old function.

void std::terminate ( )

The runtime will call this function if exception handling must be abandoned for any reason. It can also be called by the user.

template<typename _Ex >
void std::throw_with_nested ( _Ex  __ex) [inline]

If __ex is derived from nested_exception, __ex. Else, an implementation-defined object derived from both.

Definition at line 136 of file nested_exception.h.

[18.6.4]/1: 'Returns true after completing evaluation of a throw-expression until either completing initialization of the exception-declaration in the matching handler or entering unexpected() due to the throw; or after entering terminate() for any reason other than an explicit call to terminate(). [Note: This includes stack unwinding [15.2]. end note]'

2: 'When uncaught_exception() is true, throwing an exception can result in a call of terminate() (15.5.1).'

Referenced by std::basic_ostream< _CharT, _Traits >::sentry::~sentry().

void std::unexpected ( )

The runtime will call this function if an exception is thrown which violates the function's exception specification.
