 This function implements the "giet_fat_lseek()" system call.
 It repositions the offset in the file defined by the file descriptor, according to the offset and whence arguments.
-The accepted values for the whence argument are SEEK_SET and SEEK_CUR:
+The accepted values for the whence argument are SEEK_SET / SEEK_CUR / SEEK_END :
  * SEEK_SET =>  new_offset = offset
  * SEEK_CUR =>  new_offset = current_offset + offset
+ * SEEK_END => new_offset = file_size + offset
 Arguments:
  * '''fd_id''' : file descriptor index 
  * '''offset''' : offset value (can be negative)
- * '''whence''' : SEEK_SET / SEEK_CUR 
+ * '''whence''' : SEEK_SET / SEEK_CUR / SEEK_END
 Returns new seek value (in bytes) on success. Returns a negative value on error:
  * GIET_FAT32_NOT_INITIALIZED,
