.SH NAME
wmemcmp \- compare two arrays of wide-characters
.SH SYNOPSIS
.nf
.B #include <wchar.h>
.sp
.BI "int wmemcmp(const wchar_t *" s1 ", const wchar_t *" s2 ", size_t " n );
.fi
.SH DESCRIPTION
The
.BR wmemcmp ()
function is the wide-character equivalent of the
.BR memcmp (3)
function.
It compares the
.IR n
wide-characters starting at
.I s1
and the
.I n
wide-characters starting at
.IR s2 .
.SH RETURN VALUE
The
.BR wmemcmp ()
function returns
zero if the wide-character arrays of size
.I n
at
.IR s1
and
.I s2
are equal.
It returns an integer greater than
zero if at the first differing position
.I i
.RI ( i " <"
.IR n ),
the
corresponding wide-character
.I s1[i]
is greater than
.IR s2[i] .
It returns an integer less than zero if
at the first differing position
.I i
.RI ( i
<
.IR n ),
the corresponding
wide-character
.I s1[i]
is less than
.IR s2[i] .
.SH ATTRIBUTES
