std::basic_istream<CharT,Traits>::~basic_istream – std::basic_istream<CharT,Traits>::~basic_istream Synopsis virtual ~basic_istream(); Destructs the input stream. Notes This destructor does not perform any operation on the underlying streambuffer (rdbuf()): the destructors of the derived input streams such as std::basic_ifstream and std::basic_istringstream are responsible for calling the destructors of the streambuffers. Example // Run this code #include <sstream> #include <iostream> void print_stringbuf(std::streambuf…

std::basic_iostream<CharT,Traits>::~basic_iostream – std::basic_iostream<CharT,Traits>::~basic_iostream Synopsis virtual ~basic_iostream(); Destructs the input/output stream. Notes This destructor does not perform any operation on the underlying stream buffer (rdbuf()): the destructors of the derived streams such as std::basic_fstream and std::basic_stringstream are responsible for calling the destructors of the stream buffers.

std::basic_ios<CharT,Traits>::~basic_ios – std::basic_ios<CharT,Traits>::~basic_ios Synopsis virtual ~basic_ios(); Destroys the basic_ios object. No operations on rdbuf are performed, it is not destroyed. Notes This destructor is virtual because the base class destructor, ios_base::~ios_base is virtual.

std::basic_ifstream<CharT,Traits>::swap – std::basic_ifstream<CharT,Traits>::swap Synopsis void swap(basic_ifstream &other); (since C++ 11) Exchanges the state of the stream with those of other. This is done by calling basic_istream<CharT, Traits>::swap(other) and rdbuf()->swap(other.rdbuf()). Parameters other – stream to exchange the state with Return value (none) Example  This section is incomplete  Reason: no example See also operator= moves the file…

std::basic_fstream<CharT,Traits>::swap – std::basic_fstream<CharT,Traits>::swap Synopsis void swap(basic_fstream &other); (since C++ 11) Exchanges the state of the stream with those of other. This is done by calling basic_iostream<CharT, Traits>::swap(other) and rdbuf()->swap(other.rdbuf()). Parameters other – stream to exchange the state with Return value (none) Example  This section is incomplete  Reason: no example See also operator= moves the file…

std::basic_filebuf<CharT,Traits>::seekoff – std::basic_filebuf<CharT,Traits>::seekoff Synopsis protected: virtual pos_type seekoff( off_type off, std::ios_base::seekdir dir, std::ios_base::openmode which = std::ios_base::in | std::ios_base::out ); Repositions the file pointer, if possible, to the position that corresponds to exactly off characters from beginning, end, or current position of the file (depending on the value of dir. If the associated file is not…

std::bad_variant_access – std::bad_variant_access Synopsis Defined in header <variant> class bad_variant_access : public std::exception (since C++17) std::bad_variant_access is the type of the exception thrown in the following situations: * std::get(std::variant) called with an index or type that does not match the currently active alternative * std::visit called to visit a variant that is valueless_by_exception Member functions…

std::bad_typeid::bad_typeid – std::bad_typeid::bad_typeid Synopsis bad_typeid(); Constructs new std::bad_typeid object. The contents of the byte string returned by what() are implementation defined. Parameters (none) Exceptions (none) (until C++11) noexcept specification: (since C++11) noexcept

std::bad_typeid – std::bad_typeid Synopsis Defined in header <typeinfo> class bad_typeid : public std::exception; An exception of this type is thrown when a typeid operator is applied to a dereferenced null pointer value of a polymorphic type.  std-bad typeid-inheritance.svg Inheritance diagram Member functions               constructs a new bad_typeid object constructor (public member function) Inherited from std::exception Member…

std::bad_optional_access – std::bad_optional_access Synopsis Defined in header <optional> class bad_optional_access; (since C++17) Defines a type of object to be thrown by std::optional::value when accessing an optional object that does not contain a value.  std-bad optional access-inheritance-lwg2806.svg Inheritance diagram Member functions               constructs the exception object constructor (public member function) Inherited from std::exception Member functions destructor destroys…

std::bad_function_call – std::bad_function_call Synopsis Defined in header <functional> class bad_function_call; (since C++11) std::bad_function_call is the type of the exception thrown by std::function::operator() if the function wrapper has no target.  std-bad function call-inheritance.svg Inheritance diagram Member functions               constructs the bad_function_call object constructor (public member function)  std::bad_function_call::bad_function_call() bad_function_call() noexcept; Constructs a new instance of std::bad_function_call. Parameters (none)…

std::bad_exception::what – std::bad_exception::what Synopsis virtual const char *what() const noexcept; Returns the explanatory string. Parameters (none) Return value Pointer to a null-terminated string with explanatory information.

Initializes the object with the contents of other. Parameters other – bad_exception object to initialize with

std::bad_exception – std::bad_exception Synopsis Defined in header <exception> class bad_exception; std::bad_exception is the type of the exception thrown by the C++ runtime in the following situations: 1) If std::exception_ptr stores a copy of the caught exception and if the copy constructor of the exception object caught by std::current_exception throws an exception, the captured exception is…

std::bad_cast::bad_cast – std::bad_cast::bad_cast Synopsis bad_cast(); Constructs new std::bad_cast object. The contents of the byte string returned by what() are implementation defined. Parameters (none) Exceptions (none) (until C++11) noexcept specification: (since C++11) noexcept

std::bad_cast – std::bad_cast Synopsis Defined in header <typeinfo> class bad_cast : public std::exception; An exception of this type is thrown when a dynamic_cast to a reference type fails the run-time check (e.g. because the types are not related by inheritance), and also from std::use_facet if the requested facet does not exist in the locale.  std-bad…
