FATFS

+

The FATFS structure (file system object) holds dynamic work area of individual logical drives. It is given by application program and registerd/unregisterd to the FatFs module with f_mount function. Initialization is done on first API call after f_mount function or media change. Application program must not modify any member in this structure, or any data on the FAT volume can be collapsed.
