Defined in header <future>
const std::error_category& future_category();		(since C++11)

Obtains a reference to the static error category object for the errors related to futures and promises. The object is required to override the virtual function error_category::name() to return a pointer to the string "future". It is used to identify error codes provided in the exceptions of type std::future_error.

Parameters

(none)

Return value

a reference to the static object of unspecified runtime type, derived from std::error_category.

Exceptions

noexcept specification:  

noexcept
