Parameters

+
+
fp
+
Pointer to the open file object structure.
+
buff
+
Pointer to the data to be written.
+
btw
+
Specifies number of bytes to write in range of UINT type.
+
bw
+
Pointer to the UINT variable to return the number of bytes written. The value is always valid after the function call regardless of the result code.

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.
