std::is_error_condition_enum<std::errc>

STD：：是[医]误差[医]条件[医]enum<std：：ERRC>

Defined in header ​​
template<> struct is_error_condition_enum<std::errc> : std::true_type;​(since C++11)

指定std::errc是错误条件枚举。这使得隐式转换成为可能。std::error_condition...

继承自STD：积分[医]常量

成员常数

value statictrue (public static member constant)

成员函数

operator boolconverts the object to bool, returns value (public member function)
operator() (C++14)returns value (public member function)

成员类型

TypeDefinition
value_typebool
typestd::integral_constant<bool, value>

另见

is_error_condition_enum (C++11)identifies an enumeration as an std::error_condition (class template)
