ISWLOWER(3P) POSIX Programmer's Manual ISWLOWER(3P)PROLOGThis manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the correspond- ing Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.NAMEiswlower - test for a lowercase letter wide-character codeSYNOPSIS#include <wctype.h> int iswlower(wint_t wc);DESCRIPTIONThe 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 VALUEThe iswlower() function shall return non-zero if wc is a lowercase letter wide-character code; otherwise, it shall return 0.ERRORSNo errors are defined. The following sections are informative.EXAMPLESNone.APPLICATION USAGETo ensure applications portability, especially across natural languages, only this function and those listed in the SEE ALSO section should be used for classification of wide-character codes.RATIONALENone.FUTURE DIRECTIONSNone.SEE ALSOiswalnum(), iswalpha(), iswcntrl(), iswctype(), iswdigit(), iswgraph(), iswprint(), iswpunct(), iswspace(), iswupper(), iswxdigit(), setlo- cale(), the Base Definitions volume of IEEE Std 1003.1-2001, Chapter 7, Locale, <wchar.h>, <wctype.h>COPYRIGHTPortions of this text are reprinted and reproduced in electronic form from IEEE Std 1003.1, 2003 Edition, Standard for Information Technol- ogy -- Portable Operating System Interface (POSIX), The Open Group Base Specifications Issue 6, Copyright (C) 2001-2003 by the Institute of Electrical and Electronics Engineers, Inc and The Open Group.
