const BYTE* Buffer为什么要定义成const 型的啊?-
- FRESULT f_write (
- FIL* FileObject, /* Pointer to the file object structure */
- const BYTE* Buffer, /* Pointer to the data to be written */
- UINT ByteToWrite, /* Number of bytes to write */
- UINT* ByteWritten /* Pointer to the variable to return number of bytes written */
- );
