template< class... Args > void emplace_back( Args&&... args ); (since C++11) Appends a new element to the end of the container. The element is constructed through std::allocator_traits::construct, which typically uses placement-new to construct the element in-place at the location provided by the container. The arguments args... are forwarded to the constructor as std::forward<Args>(args).... If the new size() is greater than capacity() then all iterators and referen

void notify_one(); (since C++11) If any threads are waiting on *this, calling notify_one unblocks one of the waiting threads. Parameters (none). Return value (none). Exceptions noexcept specification: noexcept Notes The effects of notify_one()/notify_all() and wait()/wait_for()/wait_until() take place in a single total order, so it's impossible for notify_one() to, for example, be delayed and unblock a thread that started waiting just after the call to notify_one() was mad

void reset(); (since C++11) Resets the internal state of the distribution object. After a call to this function, the next call to operator() on the distribution object will not be dependent on previous calls to operator(). Parameters (none). Return value (none). Complexity Constant.

Defined in header <codecvt> template< class Elem, unsigned long Maxcode = 0x10ffff, std::codecvt_mode Mode = (std::codecvt_mode)0 > class codecvt_utf16 : public std::codecvt<Elem, char, std::mbstate_t>;; std::codecvt_utf16 is a std::codecvt facet which encapsulates conversion between a UTF-16 encoded byte string and UCS2 or UCS4 character string (depending on the type of Elem). This codecvt facet can be used to read and write UTF-16 files in

Defined in header <memory> template< class T > T* undeclare_reachable( T* p ); (since C++11) Removes the reachable status of the object, referenced by the pointer p, if it was previously set by std::declare_reachable. If the object was declared reachable multiple times, equal number of calls to undeclare_reachable would be needed to remove this status. Once the object is not declared reachable and has no pointers referencing it, it may be reclaimed by garbage collecto

Defined in header <cwchar> std::size_t mbrtowc( wchar_t* pwc, const char* s, std::size_t n, std::mbstate_t* ps ); Converts a narrow multibyte character to a wide character. If s is not a null pointer, inspects at most n bytes of the multibyte character string, beginning with the byte pointed to by s to determine the number of bytes necessary to complete the next multibyte character (including any shift sequences

void close(); Closes the associated file. Effectively calls rdbuf()->close(). If an error occurs during operation, setstate(failbit) is called. Parameters (none). Return value (none). Notes This function is called by the destructor of basic_ofstream when the stream object goes out of scope and is not usually invoked directly. Example See also is_open checks if the stream has an associated file (public member function) open opens a file and associates it with t

T& at( const Key& key ); (1) (since C++11) const T& at( const Key& key ) const; (2) (since C++11) Returns a reference to the mapped value of the element with key equivalent to key. If no such element exists, an exception of type std::out_of_range is thrown. Parameters key - the key of the element to find Return value Reference to the mapped value of the requested element. Exceptions std::out_of_range if the container does not have an element with t

Defined in header <locale> template< class CharT, bool International = false > class moneypunct; The facet std::moneypunct encapsulates monetary value format preferences. Stream I/O manipulators std::get_money and std::put_money use std::moneypunct through std::money_get and std::money_put for parsing monetary value input and formatting monetary value output. Inheritance diagram. Four standalone (locale-independent) specializations are provided by the standard l

static T max(); (until C++11) static constexpr T max(); (since C++11) Returns the maximum finite value representable by the numeric type T. Meaningful for all bounded types.
