 This function implements the "giet_fat_read()" system call.
 It accesses the File_Cache associated to the file identified by the file descriptor, and transfers "count" bytes from the cache to the user buffer, starting from the current file offset.
 In case of miss in the File_Cache, it loads all involved clusters into the cache.
  * '''fd_id''' : file descriptor index 
- * '''buffer''' : pointer on the memory buffer
- * '''count''' : number of bytes 
+ * '''buffer''' : pointer to the memory buffer
+ * '''count''' : number of bytes
+ * '''phys''' : use _physical_memcpy instead of memcpy
 Returns the number of bytes actually transfered on success. Returns 0 if EOF is encountered (offset + count > file_size). Returns a negative value on error:
  * GIET_FAT32_NOT_INITIALIZED,
