       24 +The \fBtolower()\fR function has as a domain of type \fBint\fR, the value of
  25   25  which is representable as an \fBunsigned char\fR or the value of \fBEOF\fR. If
  26   26  the argument has any other value, the argument is returned unchanged. If the
  27   27  argument of \fBtolower()\fR represents an upper-case letter, and there exists a
  28   28  corresponding lower-case letter (as defined by character type information in
  29   29  the locale category \fB\fR\fBLC_CTYPE\fR\fB), \fR the result is the
  30   30  corresponding lower-case letter. All other arguments in the domain are returned
  31   31  unchanged.
  32   32  .LP
  33   33  The function \fBtolower_l()\fR behaves identically to \fBtolower()\fR, except
  34   34  instead of operating in the current locale, it operates in the locale
  35   35  specified by \fIloc\fR.
       36 +.LP
       37 +A macro form, \fB_tolower()\fR exists. It is defined for standards
       38 +conformance, particularly with legacy standards. It was deprecated in
       39 +POSIX 2008 (Issue 7), and its use is discouraged. The macro, on this
       40 +system, is just an alias for \fBtolower()\fR.
  36   41  .SH RETURN VALUES
  37   42  .LP
  38   43  On successful completion, \fBtolower()\fR returns the lower-case letter
  39   44  corresponding to the argument passed. Otherwise, it returns the argument
  40   45  unchanged.
