   8 .SH NAME
   9 tolower, tolower_l \- transliterate upper-case characters to lower-case
  10 .SH SYNOPSIS

  22 .SH DESCRIPTION
  23 .LP
  24 The \fBtolower()\fR function has as a domain a type \fBint\fR, the value of
  25 which is representable as an \fBunsigned char\fR or the value of \fBEOF\fR. If
  26 the argument has any other value, the argument is returned unchanged. If the
  27 argument of \fBtolower()\fR represents an upper-case letter, and there exists a
  28 corresponding lower-case letter (as defined by character type information in
  29 the locale category \fB\fR\fBLC_CTYPE\fR\fB), \fR the result is the
  30 corresponding lower-case letter. All other arguments in the domain are returned
  31 unchanged.
  32 .LP
  33 The function \fBtolower_l()\fR behaves identically to \fBtolower()\fR, except
  34 instead of operating in the current locale, it operates in the locale
  35 specified by \fIloc\fR.





  36 .SH RETURN VALUES
  37 .LP
  38 On successful completion, \fBtolower()\fR returns the lower-case letter
  39 corresponding to the argument passed. Otherwise, it returns the argument
  40 unchanged.

  22 .SH DESCRIPTION
  23 .LP
  24 The \fBtolower()\fR function has as a domain of type \fBint\fR, the value of
  25 which is representable as an \fBunsigned char\fR or the value of \fBEOF\fR. If
  26 the argument has any other value, the argument is returned unchanged. If the
  27 argument of \fBtolower()\fR represents an upper-case letter, and there exists a
  28 corresponding lower-case letter (as defined by character type information in
  29 the locale category \fB\fR\fBLC_CTYPE\fR\fB), \fR the result is the
  30 corresponding lower-case letter. All other arguments in the domain are returned
  31 unchanged.
  32 .LP
  33 The function \fBtolower_l()\fR behaves identically to \fBtolower()\fR, except
  34 instead of operating in the current locale, it operates in the locale
  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.
  41 .SH RETURN VALUES
  42 .LP
  43 On successful completion, \fBtolower()\fR returns the lower-case letter
  44 corresponding to the argument passed. Otherwise, it returns the argument
  45 unchanged.
