Classes

class  __cxxabiv1::__forced_unwind
 Thrown as part of forced unwinding.A magic placeholder class that can be caught by reference to recognize forced unwinding. More...
struct  __gnu_cxx::forced_exception_error
 Thown by throw_allocator. More...
class  std::bad_alloc
 Exception possibly thrown by new.bad_alloc (or classes derived from it) is used to report allocation errors from the throwing forms of new. More...
class  std::bad_cast
 Thrown during incorrect typecasting.If you attempt an invalid dynamic_cast expression, an instance of this class (or something derived from this class) is thrown. More...
class  std::bad_exception
class  std::bad_typeid
 Thrown when a NULL pointer in a typeid expression is used. More...
class  std::domain_error
class  std::exception
 Base class for all library exceptions. More...
class  std::invalid_argument
class  std::ios_base::failure
 These are thrown to indicate problems with io.27.4.2.1.1 Class ios_base::failure. More...
class  std::length_error
class  std::lock_error
 Thrown to indicate errors with lock operations. More...

class  std::range_error
class  std::regex_error
 A regular expression exception class.The regular expression library throws objects of this class on error. More...
class  std::runtime_error
 One of two subclasses of exception. More...

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 86 of file exception.

typedef void(* std::unexpected_handler)()

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

Definition at line 89 of file exception.

Function Documentation

void __gnu_cxx::__verbose_terminate_handler ( )

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) throw ()

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

Definition at line 152 of file exception_ptr.h.

References std::current_exception().

exception_ptr std::current_exception ( ) throw ()

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().

void std::rethrow_exception ( exception_ptr  )

Throw the object pointed to by the exception_ptr.

terminate_handler std::set_terminate ( terminate_handler  ) throw ()

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

unexpected_handler std::set_unexpected ( unexpected_handler  ) throw ()

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.

bool std::uncaught_exception ( ) throw ()

[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 @c uncaught_exception() is true, throwing an %exception can result in a call of @c 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.
