std::is_error_condition_enum - cppreference.com (original) (raw)
| | | | | ------------------------------------------------------- | | ------------- | | template< class T > struct is_error_condition_enum; | | (since C++11) |
If T is an error condition enum (such as std::errc), this template provides the member constant value equal true. For any other type, value is false.
This template may be specialized for a program-defined type to indicate that the type is eligible for std::error_condition implicit conversions.
