virtual bool equivalent( int code, 
                         const std::error_condition& condition ) const;

(1)

(since C++11)

virtual bool equivalent( const std::error_code& code,
                         int condition ) const;

(2)

(since C++11)

Checks whether error code is equivalent to an error condition for the error category represented by *this.

1) Equivalent to default_error_condition(code) == condition.

2) Equivalent to *this == code.category() && code.value() == condition.

code	-	specifies the error code to compare
condition	-	specifies the error condition to compare

true if the error code is equivalent to the given error condition for the error category represented by *this, false otherwise.
