virtual std::error_condition default_error_condition( int val ) const noexcept;		(since C++11)

Returns the error condition for the given error value.

Equivalent to std::error_condition(val, *this).

Classes derived from error_category may override this function to map certain error values to a generic category. For example, std::system_category overrides this function to map the error values that match POSIX errno values to std::generic_category.

Parameters

val

-

error value for which to return error condition

Return value

The error condition for the given error code.
