+=== __unsigned int '''_cluster_allocate'''( fat_inode_t*   inode , unsigned int*  cluster )__ ===
+This function allocates one cluster in FAT to a file (or directory) identified by the <inode> argument. The allocated cluster index is returned in the <cluster> argument. It allocates also the associated buffers and buffer descriptors in Cache-File. It calls _get_fat_entry() and _set_fat_entry() functions to update the clusters chaining in the Cache-Fat. 
+The FAT region and the FS-INFO sector on block device are updated.

 === __unsigned int '''_clusters_release'''( fat_node_t* inode )__ ===
 This function releases all clusters allocated to a file or directory identified by the <inode> argument, until the end of the FAT linked list. It calls _get_fat_entry() and _set_fat_entry() functions to scan the FAT, and to update the clusters chaining. The FAT region and the FS-INFO sector on block device are updated.
