* Fixed f_mkdir() on FAT32 creates incorrect directory.
|
||||
* Feb 03,'08 R0.05a Added f_truncate() and f_utime().
|
||||
* Fixed off by one error at FAT sub-type determination.
|
||||
* Fixed btr in f_read() can be mistruncated.
|
||||
* Fixed cached sector is not flushed when create and close
|
||||
* without write.
|
||||
*
|
||||
* Apr 01,'08 R0.06 Added fputc(), fputs(), fprintf() and fgets().
|
||||
* Improved performance of f_lseek() on moving to the same
|
||||
* or following cluster.
