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.

       Since
           C++11
