WMEMCMP(3P)		   POSIX Programmer's Manual		   WMEMCMP(3P)

PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the	 corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.

NAME
       wmemcmp — compare wide characters in memory

SYNOPSIS
       #include <wchar.h>

       int wmemcmp(const wchar_t *ws1, const wchar_t *ws2, size_t n);

DESCRIPTION
       The functionality described on this reference page is aligned with  the
       ISO C  standard.	 Any  conflict between the requirements described here
       and the ISO C standard is unintentional. This  volume  of  POSIX.1‐2008
       defers to the ISO C standard.

       The wmemcmp() function shall compare the first n wide characters of the
       object pointed to by ws1 to the first n wide characters of  the	object
       pointed	to  by ws2.  This function shall not be affected by locale and
       all wchar_t values shall be treated identically. The null wide  charac‐
       ter  and wchar_t values not corresponding to valid characters shall not
       be treated specially.

       If n is zero, the application shall ensure that ws1 and ws2  are	 valid
       pointers,  and  the function shall behave as if the two objects compare
       equal.

RETURN VALUE
       The wmemcmp() function shall return an integer greater than, equal  to,
       or  less	 than  zero,  respectively, as the object pointed to by ws1 is
       greater than, equal to, or less than the object pointed to by ws2.
