The file pointer can be repositioned by using fseek or rewind , but it is always moved back to the end of the file before any write operation is carried out. Thus, existing data cannot be overwritten. However, when you switch between reading and writing, there must be an intervening fflush , fsetpos , fseek , or rewind operation.
