ISWLOWER(P)			    POSIX Programmer's Manual			      ISWLOWER(P)

NAME
       iswlower - test for a lowercase letter wide-character code

SYNOPSIS
       #include <wctype.h>

       int iswlower(wint_t wc);

DESCRIPTION
       The  iswlower()	function  shall  test  whether wc is a wide-character code representing a
       character of class lower in the program's current locale; see the Base Definitions  volume
       of IEEE Std 1003.1-2001, Chapter 7, Locale.

       The  wc	argument  is a wint_t, the value of which the application shall ensure is a wide-
       character code corresponding to a valid character in the current locale, or equal  to  the
       value of the macro WEOF. If the argument has any other value, the behavior is undefined.

RETURN VALUE
       The  iswlower()	function shall return non-zero if wc is a lowercase letter wide-character
       code; otherwise, it shall return 0.

ERRORS
       No errors are defined.

       character codes.

RATIONALE
