  * The '''File-Descriptor-Array''' is a statically defined array of file descriptors. According to the UNIX semantic, a private file descriptor is allocated to each task requiring to open the file, and contains mainly the current file pointer (called ''offset''). The max number of file descriptors is defined by the GIET_OPEN_FILES_MAX global variable (in the ''get_config.h'' file).
 
- * The global '''Fat-Descriptor''' contains general information such as the FAT region lba and size, the DATA region lba and size,  pointers on the Fat-Cache or Inode-Tree, the File-Descriptor-Array, and the locks protecting the FAT shared structures. It
-contains also a single cluster buffer (4096 bytes) used in the initialization phase.

 To support various block device peripheral, this FAT32 implementation defines a generic function to transparently access various physical block devices, using the driver specified in the ''hard_config.h'' file. Five drivers are presently supported ( IOC_BDV / IOC_HBA / IOC_SDC / IOC_SPI / IOC_RDK ).
