.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 );

.SH DESCRIPTION
|
|
The
|
|
.BR wmemcmp ()
|
|
function is the wide-character equivalent of the
|
|
.BR memcmp (3)
|
|
function.
|
|
It compares the \fIn\fP wide-characters starting at \fIs1\fP and the
|
|
\fIn\fP wide-characters starting at \fIs2\fP.
|
|
.SH RETURN VALUE
|
|
The
|
|
.BR wmemcmp ()
|
|
function returns
|
|
zero if the wide-character arrays of size
|
|
\fIn\fP at \fIs1\fP and \fIs2\fP are equal.
|
|
It returns an integer greater than
|
|
zero if at the first differing position \fIi\fP (\fIi\fP < \fIn\fP), the
|
|
corresponding wide-character \fIs1[i]\fP is greater than \fIs2[i]\fP.
|
|
It returns an integer less than zero if
|
|
at the first differing position \fIi\fP
|
|
(\fIi\fP < \fIn\fP), the corresponding
|
|
wide-character \fIs1[i]\fP is less than
|
|
\fIs2[i]\fP.
