Assign the error value to the real returned variable fret. The ret variable is used to check function return values and assigning values to it on error has no effect as it is an unused value.

Thank you for the find. Please simplify these leg and use just one variable for failures, ret or fret and not both to avoid future coding errors like this one you are fixing.
