The variable retValue could be 1 or the actual value or junk value
depending upon whether pow succeeded or not. So the caller is expected to test
*error value returned first to determine if the retValue is correct or not. If
the *error is not initialized for positive cases, the value stored in *error
could be undefined. In that case, the caller could be checking the incorrect
value of *error value.
