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

Parameters

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

Return value

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