Defined in header <cwchar> wchar_t* wmemmove( wchar_t* dest, const wchar_t* src, std::size_t count ); Copies exactly count successive wide characters from the wide character array pointed to by src to the wide character array pointed to by dest. If count is zero, the function does nothing. The arrays may overlap: copying takes place as if the wide characters were copied to a temporary wide character array and then copied from the temporary array to dest. Parameters dest

result_type max() const; (since C++11) Returns the maximum value potentially generated by the distribution. Parameters (none). Return value The maximum value potentially generated by the distribution. Complexity Constant. See also min returns the minimum potentially generated value (public member function)

Defined in header <chrono> template <class ToDuration, class Clock, class Duration> constexpr time_point<Clock, ToDuration> floor(const time_point<Clock, Duration>& tp); (since C++17) Returns the largest time point t representable in ToDuration that is smaller or equal to tp. The function does not participate in the overload resolution unless ToDuration is an specialization of std::chrono::duration. Parameters tp - time point to round down

param_type param() const; (1) (since C++11) void param( const param_type& params ); (2) (since C++11) Manages the associated distribution parameter set. 1) Returns the associated parameter set. 2) Sets the associated parameter set to params. Parameters params - new contents of the associated parameter set Return value 1) The associated parameter set. 2) (none). Complexity Constant.

static std::chrono::time_point<std::chrono::high_resolution_clock> now(); (since C++11) Returns a time point representing the current point in time. Parameters (none). Return value A time point representing the current time. Exceptions noexcept specification: noexcept Example #include <iostream> #include <vector> #include <numeric> #include <chrono> volatile int sink; int main() { for (auto size = 1ull; size < 1000000000ull; size *=

Defined in header <chrono> template <class ToDuration, class Clock, class Duration> constexpr time_point<Clock, ToDuration> round(const time_point<Clock, Duration>& tp); (since C++17) Returns the nearest time point to tp representable in ToDuration, rounding to even in halfway cases. The function does not participate in the overload resolution unless ToDuration is an specialization of std::chrono::duration and std::chrono::treat_as_floating_point<ty

piecewise_constant_distribution(); (1) (since C++11) template< class InputIt1, class InputIt2 > piecewise_constant_distribution( InputIt1 first_i, InputIt1 last_i, InputIt2 first_w ); (2) (since C++11) template< class UnaryOperation > piecewise_constant_distribution( std::initializer_list<RealType> bl, UnaryOperation fw ); (3) (since C++11) template< class UnaryOperation > piecewise_con

result_type max() const; (since C++11) Returns the maximum value potentially generated by the distribution. Parameters (none). Return value The maximum value potentially generated by the distribution. Complexity Constant. See also min returns the minimum potentially generated value (public member function)

Defined in header <cwchar> const wchar_t* wmemchr( const wchar_t* ptr, wchar_t ch, std::size_t count ); wchar_t* wmemchr( wchar_t* ptr, wchar_t ch, std::size_t count ); Locates the first occurrence of wide character ch in the initial count wide characters of the wide character array pointed to by ptr. If count is zero, the function returns a null pointer. Parameters ptr - pointer to the wide character array to be examined ch - wide character

Defined in header <regex> std::regex_constants::error_type code() const; (since C++11) Returns the std::regex_constants::error_type that was passed to the std::regex_error constructor. See Also error_type (C++11) describes different types of matching errors (typedef) (constructor) constructs a regex_error object (public member function)
