reverse_iterator rbegin(); const_reverse_iterator rbegin() const; const_reverse_iterator crbegin() const; (since C++11) Returns a reverse iterator to the first element of the reversed container. It corresponds to the last element of the non-reversed container. Parameters (none). Return value Reverse iterator to the first element. Exceptions (none) (until C++11) noexcept specification: noexcept (since C++11) Complexity Constant. See also rend crend r

static constexpr result_type max(); (since C++11) Returns the maximum value potentially generated by the random-number engine. Parameters (none). Return value The maximum potentially generated value. Complexity Constant. See also min [static] gets the smallest possible value in the output range (public static member function)

Defined in header <regex> class regex_error; (since C++11) Defines the type of exception object thrown to report errors in the regular expressions library. Inheritance diagram. Member functions (constructor) constructs a regex_error object (public member function) code gets the std::regex_constants::error_type for a regex_error (public member function) Inherited from std::exception Member functions (destructor) [virtual] destructs the exce

size_type max_size() const; Returns the maximum number of elements the container is able to hold due to system or library implementation limitations, i.e. std::distance(begin(), end()) for the largest container. Parameters (none). Return value Maximum number of elements. Exceptions (none) (until C++11) noexcept specification: noexcept (since C++11) Complexity Constant. Notes This value is typically equal to std::numeric_limits<size_type>::max(), and reflects the

operator void*() const; (1) (until C++11) explicit operator bool() const; (2) (since C++11) Checks whether the stream has no errors. 1) Returns a null pointer if fail() returns true, otherwise returns a non-null pointer. This pointer is implicitly convertible to bool and may be used in boolean contexts. 2) Returns true if the stream has no errors and is ready for I/O operations. Specifically, returns !fail(). This operator makes it possible to use streams and functions that ret

Defined in header <csignal> void (*signal( int sig, void (*handler) (int))) (int); Sets the error handler for signal sig. The signal handler can be set so that default handling will occur, signal is ignored, or a user-defined function is called. When signal handler is set to a function and a signal occurs, it is implementation defined whether std::signal(sig, SIG_DFL) will be executed immediately before the start of signal handler. Also, the implementation can prevent some

int_type peek(); Behaves as UnformattedInputFunction. After constructing and testing the sentry object, reads the next character from the input stream without extracting it. Parameters (none). Return value If good() == true, returns the next character as obtained by rdbuf()->sgetc(). Otherwise, returns Traits::eof(). Exceptions failure if an error occurred (the error state flag is not goodbit) and exceptions() is set to throw for that state. If an internal operation throw

Defined in header <tuple> template< class... Types, class Alloc > struct uses_allocator< std::tuple<Types...>, Alloc > : std::true_type { }; (since C++11) This specialization of std::uses_allocator informs other library components that tuples support uses-allocator construction, even though they do not have a nested allocator_type.
