Defined in header <locale> template< class CharT, class OutputIterator = std::ostreambuf_iterator<CharT> > class time_put_byname : public std::time_put<CharT, OutputIterator>; std::time_put_byname is a std::time_put facet which encapsulates time and date formatting rules of the locale specified at its construction. Two specializations are provided by the standard library. Defined in header <locale> std::time_put_byname<char, OutputIterator>

Equivalent to (2) (the argument is cast to double). Parameters

An AllocatorAwareContainer is a Container that holds an instance of an Allocator and uses that instance to allocate and deallocate memory in all of its member functions. The following rules apply to object construction. Copy constructors of AllocatorAwareContainers obtain their instances of the allocator by calling std::allocator_traits<allocator_type>::select_on_container_copy_construction on the allocator of the container being copied. Move constructors obtain their instances of allo

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 See also operator= (C++11) moves the file stream (public member function) swap (C++11) swaps two basic_filebuf objects (public member function of std::basic_

Specifies whether a function will throw exceptions or not. Syntax noexcept (1) noexcept(expression) (2) 1) Same as noexcept ( true ) 2) If expression evaluates to true, the function is declared to not throw any exceptions. expression - constant expression, contextually convertible to bool Explanation The noexcept-specification (just like dynamic exception specification) can appear as a part of a lambda declarator or a top-level function declarator when declaring f

An OutputIterator is an Iterator that can write to the pointed-to element. An example of a type that implements OutputIterator is std::ostream_iterator. When ForwardIterator, BidirectionalIterator, or RandomAccessIterator satisfies the OutputIterator requirements in addition to its own requirements, it is described as mutable. Requirements The type X satisfies OutputIterator if. The type X satisfies Iterator X is a class type or a pointer type And, given. o, a value of some type that
