std::error_condition

std::error_condition holds a platform-independent value identifying an error condition. Like std::error_code, it is uniquely identified by an integer value and a std::error_category, but unlike std::error_code, the value is not platform-dependent.

# Declarations

class error_condition;

(since C++11)

# Notes

The comparison between a std::error_code and a std::error_condition is defined by their error categories. Notably, an error condition of std::generic_category may compare equal to an error code of a specific category (e.g. std::system_category), if they represent the same kind of error.

A std::errc value can be compared to an error code via implicit conversion to std::error_condition.
