  Depending on the implementation of the file name handler, it might not
  be possible to apply @var{filter} or @var{sentinel} to the resulting
! process object.  @xref{Filter Functions}, and @ref{Sentinels}.

  Some file name handlers may not support @code{make-process}.  In such
  cases, this function does nothing and returns @code{nil}.
