std::begin(std::valarray) – std::begin(std::valarray) Synopsis template <class T> (1)(since C++ 11) /*unspecified1*/ begin(valarray<T> &v); template <class T> (2)(since C++ 11) /*unspecified2*/ begin(const valarray<T> &v); The overload of std::begin for valarray returns an iterator of unspecified type referring to the first element in the numeric array. 1) The return type meets the requirements of mutable LegacyRandomAccessIterator. 2)…
std::begin(std::initializer_list) – std::begin(std::initializer_list) Synopsis template <class E> (since C++ 11) const E *begin(initializer_list<E> il) noexcept; (until C++ 14) template <class E> (since C++ 14) constexpr const E *begin(initializer_list<E> il) noexcept; The overload of std::begin for initializer_list returns a pointer to the first element of il. Parameters il – an initializer_list Return value il.begin() Example //…
std::basic_syncbuf<CharT,Traits,Allocator>::~basic_syncbuf – std::basic_syncbuf<CharT,Traits,Allocator>::~basic_syncbuf Synopsis ~basic_syncbuf(); Calls emit() to transmit all pending output (and delayed flush, if any) to the wrapped stream. If an exception is thrown by this call, it is caught and ignored. Parameters (none) Notes Normally called by the destructor of the owning std::basic_osyncstream. Example This section is incomplete Reason: no example See…
std::basic_stringstream::swap – std::basic_stringstream::swap Synopsis void swap(basic_stringstream &other); (since C++ 11) Exchanges the state of the stream with those of other. This is done by callingbasic_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 string stream…
std::basic_stringstream::rdbuf – std::basic_stringstream::rdbuf Synopsis std::basic_stringbuf<CharT, Traits, Allocator> *rdbuf() const; Returns pointer to the underlying raw string device object.

std::basic_stringstream::operator= – std::basic_stringstream::operator= Synopsis basic_stringstream& operator=( basic_stringstream&& other ); (since C++11) Move assigns the string stream other to *this, effectively move-assigning both the std::basic_iostream base class and the associated std::basic_stringbuf.
