The Linux Manuals (man pages) document is an important part of Linux documents. Linux Manuals are organized as several sections. Each section has a group of commands for a specific area in Linux usage, administration or development.
std::this_thread::sleep_until – std::this_thread::sleep_until Synopsis Defined in header<thread> template <class Clock, class Duration> (since C++ 11) void sleep_until(const std::chrono::time_point<Clock, Duration> &sleep_time); Blocks the execution of the current thread until specified sleep_time has been reached. The clock tied to sleep_time is used, which means that adjustments of the clock are taken into account. Thus, the duration of…
std::this_thread::sleep_for – std::this_thread::sleep_for Synopsis Defined in header<thread> template <class Rep, class Period> (since C++ 11) void sleep_for(const std::chrono::duration<Rep, Period> &sleep_duration); Blocks the execution of the current thread for at least the specified sleep_duration. This function may block for longer than sleep_duration due to scheduling or resource contention delays. The standard recommends that a steady clock…

std::terminate_handler – std::terminate_handler Synopsis Defined in header<exception> typedef void (*terminate_handler)(); std::terminate_handler is the function pointer type (pointer to function that takes no arguments and returns void), which is installed and queried by the functions std::set_terminate and std::get_terminate and called by std::terminate. The C++ implementation provides a default std::terminate_handler function, which calls std::abort(). If the null…
std::terminate – std::terminate Synopsis Defined in header <exception> void terminate(); (until C++11) [[noreturn]] void terminate() noexcept; (since C++11) std::terminate() is called by the C++ runtime when exception handling fails for any of the following reasons: 1) an exception_is_thrown and not caught (it is implementation-defined whether any stack unwinding is done in this case) 2) a…

Parameters va – value array to apply the operation to Return value Value array containing hyperbolic tangent of the values in va. Notes Unqualified function (tanh) is…
std::tanh(std::complex) – std::tanh(std::complex) Synopsis Defined in header<complex> template <class T> (since C++ 11) complex<T> tanh(const complex<T> &z); Computes complex hyperbolic tangent of a complex value z.
