!   When two users edit the same file at the same time, they are likely to
! interfere with each other.  Emacs tries to prevent this situation from

  Emacs can then detect the first attempt to modify a buffer visiting a
  file that is locked by another Emacs job, and ask the user what to do.

  This function locks the file @var{filename}, if the current buffer is
  modified.  The argument @var{filename} defaults to the current buffer's
  visited file.  Nothing is done if the current buffer is not visiting a
! file, or is not modified.
  @end defun
  
  @defun unlock-buffer
  This function unlocks the file being visited in the current buffer,
  if the buffer is modified.  If the buffer is not modified, then
  the file should not be locked, so this function does nothing.  It also

  This function returns @code{t} if you have permission to open existing
! files in the directory whose name as a file is @var{dirname}; otherwise
! (or if there is no such directory), it returns @code{nil}.  The value
! of @var{dirname} may be either a directory name or the file name of a
! file which is a directory.
