Constructor & Destructor Documentation
std::error_condition::error_condition()[inline],[noexcept]
Initialize with a zero (no error) value and the generic category.
std::error_condition::error_condition(int__v,consterror_category&__cat)[inline],[noexcept]
Initialize with the specified value and category.
template<typename_ErrorConditionEnum,typename=_Check<_ErrorConditionEnum>>std::error_condition::error_condition(_ErrorConditionEnum__e)[inline],[noexcept]
Initialize with a user-defined type, by calling make_error_condition.
Detailed Description
Class error_condition
This class represents error conditions that may be visible at an API boundary. Different error_code
values that can occur within a library or module might map to the same error_condition.
An error_condition represents something that the program can test for, and subsequently take appropriate
action.

C++11
