Description

-

The function starts to write data to the file at the position pointed by the read/write pointer. The read/write pointer advances as number of bytes written. After the function succeeded, *bw should be checked to detect the disk full. In case of *bw < btw, it means the volume got full during the write operation. The function can take a time when the volume is full or close to full.
