The FIL structure (file object) holds the state of an open file. It is created by f_open function and discarded by f_close function. Application program must not modify any member in this structure except for cltbl, or any data on the FAT volume can be collapsed. Note that a sector buffer is defined in this structure at non-tiny configuration (_FS_TINY == 0), so that the FIL structures at that configuration should not be defined as auto variable.
