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.

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 otherwise.

Exceptions
