std::timed_mutex::~timed_mutex – std::timed_mutex::~timed_mutex Synopsis ~timed_mutex(); Destroys the mutex. The behavior is undefined if the mutex is owned by any thread or if any thread terminates while holding any ownership of the mutex. See also
std::timed_mutex::native_handle – std::timed_mutex::native_handle Synopsis native_handle_type native_handle(); (since C++11) (optional) Returns the underlying implementation-defined native handle object. Parameters (none) Return value Implementation-defined native handle object. Exceptions Implementation-defined. Example This section is incomplete Reason: no example
std::timed_mutex::lock – std::timed_mutex::lock Synopsis void lock(); (since C++ 11) Locks the mutex. If another thread has already locked the mutex, a call to lock will block execution until the lock is acquired. If lock is called by a thread that already owns the mutex, the behavior is undefined: for example, the program may deadlock. An…
std::timed_mutex – std::timed_mutex Synopsis Defined in header <mutex> class timed_mutex; (since C++11) The timed_mutex class is a synchronization primitive that can be used to protect shared data from being simultaneously accessed by multiple threads. In a manner similar to mutex, timed_mutex offers exclusive, non-recursive ownership semantics. In addition, timed_mutex provides the ability to attempt to…
std::time_t – std::time_t Synopsis Defined in header <ctime> typedef /* unspecified */ time_t; Arithmetic type capable of representing times. Although not defined, this is almost always an integral value holding the number of seconds (not counting leap seconds) since 00:00, Jan 1 1970 UTC, corresponding to POSIX_time. See also returns the current time of the…
std::time_put_byname – std::time_put_byname Synopsis 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>…
std::time_put<CharT,OutputIt>::~time_put – std::time_put<CharT,OutputIt>::~time_put Synopsis Defined in header <locale> protected: ~time_put(); Destructs a std::time_put facet. This destructor is protected and virtual (due to base_class destructor being virtual). An object of type std::time_put, like most facets, can only be destroyed when the last std::locale object that implements this facet goes out of scope or if a user-defined…
std::time_get_byname – std::time_get_byname Synopsis Defined in header <locale> template< class CharT, class InputIt = std::istreambuf_iterator<CharT> > class time_get_byname : public std::time_get<CharT, InputIt> std::time_get_byname is a std::time_get facet which encapsulates time and date parsing rules of the locale specified at its construction. Two specializations are provided by the standard library Defined in header <locale> std::time_get_byname<char, InputIt>…
std::time_get<CharT,InputIt>::~time_get – std::time_get<CharT,InputIt>::~time_get Synopsis Defined in header <locale> protected: ~time_get(); Destructs a std::time_get facet. This destructor is protected and virtual (due to base_class destructor being virtual). An object of type std::time_get, like most facets, can only be destroyed when the last std::locale object that implements this facet goes out of scope or if a user-defined…
std::time_base – std::time_base Synopsis Defined in header <locale> class time_base; The class std::time_base provides the date order constants which are inherited by the std::time_get facets. Member types Member type Definition enum dateorder { no_order, dmy, mdy, ymd, ydm }; Unscoped enumeration type Enumeration constant Definition no_order Unspecified order dmy Day, month, year (european) order mdy…
std::time – std::time Synopsis Defined in header <ctime> std::time_t time( std::time_t* arg ); Returns the current calendar time encoded as a std::time_t object, and also stores it in the object pointed to by arg, unless arg is a null pointer. Parameters arg – pointer to a std::time_t object to store the time, or a null…
std::tie – std::tie Synopsis Defined in header <tuple> template< class… Types > (since C++11) tuple<Types&…> tie( Types&… args ) noexcept; (constexpr since C++14) Creates a tuple of lvalue references to its arguments or instances of std::ignore. Parameters args – zero or more lvalue arguments to construct the tuple from Return value A std::tuple object containing…
std::throw_with_nested – std::throw_with_nested Synopsis Defined in header<exception> template <class T> (since C++ 11) [[noreturn]] void throw_with_nested(T &&t); If std::decay<T>::type is a non-final non-union class type that is neither std::nested_exception nor derived from std::nested_exception, throws an exception of an unspecified type that is publicly derived from both std::nested_exception and from std::decay<T>::type, and constructed from std::forward<T>(t). The…
std::thread::id – Synopsis Public Member Functions id (native_handle_type __id) Friends class hash< thread::id > bool operator< (thread::id __x, thread::id __y) noexcept template<class _CharT , class _Traits > basic_ostream< _CharT, _Traits > & operator<< (basic_ostream< _CharT, _Traits > &__out, thread::id __id) bool operator== (thread::id __x, thread::id __y) noexcept class thread Detailed Description thread::id Definition at line…
std::thread::~thread – std::thread::~thread Synopsis ~thread(); (since C++11) Destroys the thread object. If *this has an associated thread (joinable() == true), std::terminate() is called. Notes A thread object does not have an associated thread (and is safe to destroy) after * it was default-constructed * it was moved from * join() has been called * detach()…
std::thread::swap – std::thread::swap Synopsis void swap(thread &other) noexcept; (since C++ 11) Exchanges the underlying handles of two thread objects. Parameters other – the thread to swap with Return value (none) Example // Run this code #include <iostream> #include <thread> #include <chrono> void foo() { std::this_thread::sleep_for(std::chrono::seconds(1)); } void bar() { std::this_thread::sleep_for(std::chrono::seconds(1)); } int main() { std::thread…
std::thread::operator= – std::thread::operator= Synopsis thread& operator=( thread&& other ) noexcept; (since C++11) If *this still has an associated running thread (i.e. joinable() == true), call std::terminate(). Otherwise, assigns the state of other to *this and sets other to a default constructed state. After this call, this->get_id() is equal to the value of other.get_id() prior to…
std::thread::native_handle – std::thread::native_handle Synopsis native_handle_type native_handle(); (since C++11) Returns the implementation defined underlying thread handle. Parameters (none) Return value implementation defined handle type representing the thread. Exceptions (none) Example Uses native_handle to enable realtime scheduling of C++ threads on a POSIX system // Run this code #include <thread> #include <mutex> #include <iostream> #include <chrono> #include…
std::thread::joinable – std::thread::joinable Synopsis bool joinable() const noexcept; (since C++11) Checks if the thread object identifies an active thread of execution. Specifically, returns true if get_id() != std::thread::id(). So a default constructed thread is not joinable. A thread that has finished executing code, but has not yet been joined is still considered an active thread…
std::thread::join – std::thread::join Synopsis void join(); (since C++ 11) Blocks the current thread until the thread identified by *this finishes its execution. The completion of the thread identified by *this synchronizes with the corresponding successful return from join(). No synchronization is performed on *this itself. Concurrently calling join() on the same std::thread object from multiple…
