-=== __unsigned int '''_add_dir_entry'''( fat_inode_t* child , fat_inode_t* parent )__ ===
-This function add a new <child> entry in the Cache-File of the <parent> directory. It accesses the File_Cache associated to the parent directory, and scan the clusters allocated to this directory to find the NO_MORE entry, that will be the first modified entry in the directory.
-Regarding the name storage, it uses LFN entries for all names, but computes a legal (upper case / 8-3) SFN name that will be stored in the NORMAL entry.
+=== __unsigned int '''_add_dir_entry'''( fat_inode_t* child )__ ===
+This function add a new <child> entry in the Cache-File of the parent directory, and update the "dentry" field in the child inode. This field contains the NORMAL directory entry in the parent directory. It accesses the File_Cache associated to the parent directory, and scan the clusters allocated to this directory to find the NO_MORE entry, that will be the first modified entry in the directory. Regarding the name storage, it uses LFN entries for all names, but computes a legal (upper case / 8-3) SFN name that will be stored in the NORMAL entry.
 It writes 1, 2, or 3 LFN entries (depending on the child name actual length), writes one NORMAL entry, and writes the new NO_MORE entry.
 It updates the dentry field in the child inode. It set the dirty bit for all modified File-Cache buffers.
