Detailed Description

VFS interface for a FAT filesystem.

This file defines the public interface to add support for the FAT filesystem, as in common use on all kinds of systems and popularized by MS-DOS and Windows. This interface supports FAT12, FAT16, and FAT32, with both short and long names.

Note that there is a lower-level interface sitting underneath of this layer. This lower-level interface (simply called fatfs) should not generally be used by any normal applications. As of this point, it is completely non thread-safe and the fs_fat layer takes extreme care to overcome those issues with the lower-level interface. Over time, I may fix the thread- safety issues in fatfs, but that is not particularly high on my priority list at the moment. There shouldn't really be a reason to work directly with the fatfs layer anyway, as this layer should give you everything you need by interfacing with the VFS in the normal fashion.
