Updating "ppos" on error conditions does not make much sense. The pattern is to return the error code directly without modifying the position, or modify the position on success and return the number of bytes written. Since on success, the return value of apply is 0, there is no point in modifying ppos either. Fix it by removing all this and just returning error code or number of bytes written on success.
